Functions, Domains & Function Notation
What Is a Function?
A function is a relation between two sets — the domain (set of allowable inputs) and the codomain (set of possible outputs) — where every element of the domain is mapped to exactly one element of the codomain. This is the defining property: one input, one output. No x-value may be paired with two different y-values.
We write f : A → B, read "f is a function from A to B", where A is the domain and B is the codomain. The rule of the function tells us what to do to each input. For example, f : ℝ → ℝ, f(x) = x² maps every real number to its square.
Distinguishing functions from non-functions: The vertical line test is the graphical check — a relation is a function if and only if every vertical line drawn through the graph intersects it at most once. For instance, the circle x² + y² = 4 is a relation but not a function, because the vertical line x = 0 intersects it at (0, 2) and (0, −2).
Worked Example: Is y² = x a function?
Choose x = 4. Then y² = 4, so y = 2 or y = −2. The input x = 4 produces two outputs, so this is not a function. ✓
By contrast, y = x² is a function: for each x, x² produces exactly one value. The vertical line test confirms: every vertical line hits the parabola at most once. ✓
Note: in Methods, functions are typically real-valued and defined on real-number domains. The notation f(x) denotes the output (or image) of x under f, and is read "f of x".
Domain, Codomain and Range
The domain of a function is the complete set of input values for which the rule is defined and produces a real output. The range (also called the image) is the actual set of output values produced — it is always a subset of the codomain.
Maximal domain: when no domain is stated, we assume the maximal (natural) domain — the largest subset of ℝ for which the rule yields a real number. Three key restrictions apply:
- You cannot divide by zero: exclude any x that makes a denominator equal zero.
- You cannot take the square root (or any even root) of a negative number (in the reals): exclude any x that makes the expression under the radical negative.
- You cannot take the logarithm of zero or a negative number: for loga(g(x)), require g(x) > 0.
Worked Example 1 — Rational function: Find the maximal domain of f(x) = 3/(x − 2).
Denominator: x − 2 ≠ 0 ⟹ x ≠ 2.
Maximal domain: ℝ \ {2} = (−∞, 2) ∪ (2, +∞). ✓
Worked Example 2 — Square root function: Find the maximal domain and range of f(x) = √(9 − x²).
Require 9 − x² ≥ 0 ⟹ x² ≤ 9 ⟹ −3 ≤ x ≤ 3.
Maximal domain: [−3, 3].
Now find the range: √(9 − x²) ≥ 0 always, and the maximum occurs at x = 0: √9 = 3. As x → ±3, √(9 − x²) → 0.
Range: [0, 3]. ✓ (Geometrically, this is the upper semicircle of radius 3.)
Worked Example 3 — Logarithmic function: Find the maximal domain of f(x) = loge(2x − 6).
Require 2x − 6 > 0 ⟹ 2x > 6 ⟹ x > 3.
Maximal domain: (3, +∞). ✓
Range: loge of a positive quantity ranges over all of ℝ, so range = ℝ.
When a domain is specified, the range must be determined by examining the function's behaviour (including turning points, endpoints, and asymptotes) over that restricted domain — not the maximal domain.

VCE Maths Methods revision: work from the first incorrect step
Separate a concept gap from an algebra slip or an incorrect domain. In a functions question, state the permitted inputs before solving. In calculus, identify what the derivative or integral represents in the problem. In probability, define the event and the model before entering values.
The hub brings functions, calculus and probability notes together with worked practice. Try a question without looking at its answer, compare the first point where your reasoning diverges, then redo that step with different values. Use the technology-free and technology-assisted tasks appropriate to the paper you are preparing for.
Common questions about VCE Mathematical Methods
What is the difference between Methods Exam 1 and Exam 2?
Exam 1 is a short-answer paper worked without technology, so the marks are in exact values and visible algebra — derivatives, anti-derivatives, log laws and sketches by hand. Exam 2 has a multiple-choice section followed by extended-response questions and assumes approved technology, so it can ask for numerical solutions and answers correct to a stated number of decimal places.
Which study design does VCE Mathematical Methods follow now?
The current design covers Units 1 to 4 from 2023 to 2027, so exams from 2023 onwards are set against it. Papers from 2016 to 2022 belong to the previous accreditation period, and 2015 and earlier were sat as Mathematical Methods (CAS) under an older design, which is why the file names and question styles change at those boundaries.
Is pseudocode examinable in Mathematical Methods?
Yes. Algorithmic thinking sits inside the current study design, and it has already appeared in the examination — a 2024 Exam 2 multiple-choice item required tracing a pseudocode routine to work out the order in which it printed the roots of a cubic. You need to be able to follow a loop and a conditional accurately by hand.
How much statistical inference is on the Methods exams?
Enough that it cannot be skipped. Sample proportions and approximate confidence intervals appear on both papers — the 2024 Exam 1 required constructing a 95% interval and finding a minimum sample size, and Exam 2 asked for a 90% interval plus the range of sample counts consistent with a given interval.
Does VCE Mathematical Methods scale up or down?
Mathematical Methods scales up solidly. In the 2025 VTAC scaling report a raw study score of 30 scaled to 35. Scaling is recalculated every year, so this describes a past cohort rather than the year you are sitting.
