What will I learn?
Function notation, domains and ranges
Accredited course guide — check versionA function includes its domain. Find every algebraic and contextual input restriction, then determine outputs actually attained, checking vertices, endpoints and excluded values.
Polynomial factorisation, binomial expansion and graph features
Accredited course guide — check versionUse factors to reveal zeros and multiplicities, expanded form to reveal coefficients, and derivative signs when stationary-point classification is required. Check reconstructed expressions against every condition.
Exponential and logarithmic functions and modelling
Accredited course guide — check versionExponentials describe multiplicative change; logarithms recover exponents. Preserve domain restrictions, isolate the exponential component, and distinguish limiting levels from attained outputs.
Transformations, composites, inverses and piecewise functions
Accredited course guide — check versionTrack coordinates through transformations, check both stages of a composite, and exchange domain and range when inverting. Preserve excluded inputs and distinguish matching heights from matching gradients.
Radians, the unit circle and exact values
Accredited course guide — check versionUse radians consistently, derive exact magnitudes from special triangles, and use the unit circle for signs and periodicity. Quadrant information resolves square-root choices in identity calculations.
Trigonometric identities and symmetry
Accredited course guide — check versionDerive signs from unit-circle symmetry, use identities within their domains, and preserve excluded and zero cases when simplifying or solving.
Circular graphs, transformations and equations
Accredited course guide — check versionUse amplitude, period and phase to sketch circular functions, transform the angle domain before solving, and justify that every branch and allowed endpoint has been considered.
Periodic modelling and interpretation
Accredited course guide — check versionBuild amplitude and midline from extrema, determine the true cycle interval, anchor the phase to an event, and turn threshold roots into contextual time intervals.
Limits, first principles and differentiability
Accredited course guide — check versionDerive rates by simplifying a nonzero-step difference quotient before taking its limit. Check both sides at joins and distinguish function values, slopes and stationary-point classifications.
Product, quotient and chain rules
Accredited course guide — check versionIdentify the outer operation, apply its rule, and differentiate each nested piece with its own chain factors. Preserve domains and check representative slopes before interpreting tangents or stationary points.
Tangents, normals and derivative graphs
Accredited course guide — check versionUse the original function for contact points and its derivative for directions. Handle vertical normals explicitly, solve for unknown contact inputs, and distinguish derivative slopes from original heights.
Stationary points, optimisation and motion
Accredited course guide — check versionClassify stationary candidates with local signs, compare all feasible candidates for global extrema, and interpret motion through velocity signs rather than position alone.
Antiderivatives and boundary conditions
Accredited course guide — check versionIntegrate to a family, apply every supplied condition to the correct function, and differentiate the completed answer as a check. Preserve domain restrictions and distinguish position from change in position.
Definite integrals and the fundamental theorem
Accredited course guide — check versionEvaluate signed accumulation through antiderivative endpoint differences, preserve orientation, and use additivity or supplied derivative relationships before attempting unnecessary algebra.
Areas under and between curves
Accredited course guide — check versionLocate boundaries and crossings first, integrate non-negative vertical separations piece by piece, and check both the geometry and the units before reporting total area.
Recovering functions and modelling displacement
Accredited course guide — check versionRecover changes through definite integrals, attach initial levels for positions or amounts, and split signed motion or piecewise rates where interpretation requires it.
Discrete random variables, expectation and variance
Accredited course guide — check versionBuild a valid probability table, calculate weighted moments accurately, and distinguish long-run averages from individual outcomes and event probabilities.
Binomial distributions and modelling assumptions
Accredited course guide — check versionCheck the trial assumptions, define the count event precisely, and use complements and integer boundary checks to make binomial calculations complete and interpretable.
Normal probabilities, quantiles and inverse parameters
Accredited course guide — check versionUse density areas for continuous probabilities, standardise with the correct spread, and translate tail statements carefully before cumulative or inverse-normal calculations.
Sample proportions and confidence intervals
Accredited course guide — check versionDistinguish the unknown population parameter from the sample estimate, use the appropriate sampling spread, and interpret confidence as procedural coverage while checking sample quality and approximation conditions.
How will I be assessed?
School arrangements: TASC course assessment applies to the accredited course and level, whether you take it in Year 11 or Year 12. Check criteria, work requirements and any external assessment in the course document, plus your provider’s internal assessment outline.
Needs verification: Accredited course guide (Mathematics Methods Level 4 (MTM415117), version 1e, re-accredited by TASC as ongoing from 1 January 2026 (no expiry date), so it applies in 2027; External Assessment Specifications Version 1.2 (February 2022) and the updated 2025 assessment report (September 2026).): The architecture is 80+100=180 numeric marks. The 2025 report excludes Q47(b), resulting in 178 assessed marks that year; this historical adjustment is not the current practice-paper total. External ratings for criteria 4–8 supplement internal criterion ratings; do not invent a percentage weighting. Confirm the syllabus and assessment schedule for your own completion year.
Progression and companion subjects
No complete companion or exclusion review is attached to this profile. Check the official course-entry conditions, language eligibility and your school’s sequence before enrolling. Links between resource hubs show related learning; they do not establish a compulsory prerequisite.
Will I find it hard?
Difficulty depends on your experience, interests, teaching and assessment. These are our reflection prompts, not an official difficulty rating.
- How do you feel about explaining a method and working through unfamiliar multi-step problems?
- Try the sample without looking at a worked answer, then check the steps you need to practise.
Does it scale up or down?
TASC awards and scaled TE scores are distinct. The old requirement for three final-year results was removed from 2025.

Try a little of the subject
Function notation, domains and ranges
1. A function is a rule with an input set A function assigns exactly one output to each allowed input. Its definition therefore needs both a rule and a domain. The expression f(x)=x² is not enough to settle every question about f: a function on all real numbers behaves differently from the same rule restricted to x≥0. Both satisfy the vertical line test, but only the restricted version has a single-valued inverse. Distinguish the independent variable x from the output f(x); f is the name of the mapping, not a number to multiply by x. For f(x)=3x²−2x+1, evaluate a function by replacing every occurrence of x with the entire input in brackets. Thus f(−2)=3(−2)²−2(−2)+1=17. For an algebraic input, f(a+1)=3(a+1)²−2(a+1)+1=3a²+4a+2. This is not f(a)+1, which equals 3a²−2a+2. The two expressions describe different operations: one changes the input before applying f, while the other changes its output afterwards. This distinction later controls horizontal and vertical graph translations. Function equations ask a different question from evaluation. To solve f(x)=1 here, write 3x²−2x+1=1, then x(3x−2)=0. The inputs are x=0 and x=2/3, subject to the stated domain. If the domain were [1,4], neither would be allowed, so the restricted function would have no preimage of 1. Do not silently replace the given domain with the largest algebraically possible one. As a check, substitute each candidate into the original rule rather than only into a transformed equation. In written solutions, distinguish an output statement such as f(−2)=17 from an input solution such as x=−2. 2. Finding a maximal real domain The maximal real domain consists of all real inputs for which the stated expression is defined. A denominator cannot be zero, an even root needs a non-negative radicand, and a logarithm
Original practice question: Let f(x)=√(9−x²)/(x−1). Determine its maximal real domain, all intercepts, and whether either radicand endpoint is excluded. Explain each restriction.
