A Level Maths Algebra and Functions revision

Algebra and functions is the largest pure topic and the one every other topic leans on. Fluent index laws, surds, quadratics and polynomial division save time on every paper.

What you need to know

Algebra and Functions in Year 12 and Year 13

AS content is usually taught in Year 12. The full A Level adds the Year 13 content.

Year 12 (AS content)

  • Indices and surds, including rationalising the denominator
  • Quadratic functions: the discriminant, completing the square, solving and sketching
  • Simultaneous equations (one linear, one quadratic) and linear and quadratic inequalities
  • Expanding, factorising and dividing polynomials; the factor theorem
  • Sketching curves, including cubics, quartics and reciprocal graphs, and graph transformations

Year 13 (full A Level only)

  • The modulus function and modulus equations and inequalities
  • Composite and inverse functions, domain and range
  • Simplifying algebraic fractions and partial fractions
  • Combining transformations, including y = |f(x)|

Worked examplemedium5 marks

Express the rational function $\frac{5x - 3}{(x+1)(x-3)}$ in partial fractions.

Mark scheme and worked answer

M1 for setting up the decomposition: $\frac{5x - 3}{(x+1)(x-3)} = \frac{A}{x+1} + \frac{B}{x-3}$.
M1 for clearing denominators: $5x - 3 = A(x - 3) + B(x + 1)$.
M1 for substituting $x = 3$ to find $B$: $15 - 3 = 4B \implies 12 = 4B$.
A1 for finding $B = 3$.
M1 for substituting $x = -1$ to find $A$: $-5 - 3 = -4A \implies -8 = -4A$.
A1 for finding $A = 2$ and stating the final expression: $\frac{2}{x+1} + \frac{3}{x-3}$.

Question 3hard4 marks

A cubic curve crosses the x-axis at $x = -2$, $x = 1$, and $x = 4$. It crosses the y-axis at the point $(0, 16)$. Find the equation of the curve in the form $y = ax^3 + bx^2 + cx + d$.

Algebra and Functions: common questions

Is algebra and functions on the AQA, Edexcel and OCR A Level Maths exams?

Yes. Algebra and Functions is part of the A Level Maths content that every board examines: AQA section B, Edexcel Pure 2, OCR 1.02. It is assessed in AQA Paper 1, and Section A of Papers 2 and 3; Edexcel Paper 1 and Paper 2; OCR A Paper 1, and the pure sections of Papers 2 and 3.

Is algebra and functions Year 12 or Year 13 content?

Both. The AS content, usually taught in Year 12, is: Indices and surds, including rationalising the denominator; Quadratic functions: the discriminant, completing the square, solving and sketching; Simultaneous equations (one linear, one quadratic) and linear and quadratic inequalities; Expanding, factorising and dividing polynomials; the factor theorem; Sketching curves, including cubics, quartics and reciprocal graphs, and graph transformations. The full A Level adds: The modulus function and modulus equations and inequalities; Composite and inverse functions, domain and range; Simplifying algebraic fractions and partial fractions; Combining transformations, including y = |f(x)|.

Which algebra topics come up most?

Quadratics (discriminant and completing the square), the factor theorem and curve sketching appear on almost every paper. In Year 13, composite and inverse functions and partial fractions are the most common.
