A12recognise, sketch and interpret graphs of linear functions, quadratic functions, simple cubic functions, the reciprocal function y = 1/x with x ≠ 0, exponential functions y = k^x for positive values of k, and the trigonometric functions (with arguments in degrees) y = sin x, y = cos x and y = tan x for angles of any size

GCSE subject content

GCSE specifications in mathematics should require students to recognise, sketch and interpret graphs of linear functions, quadratic functions, simple cubic functions, the reciprocal function y = 1/x with x ≠ 0, exponential functions y = k^x for positive values of k, and the trigonometric functions (with arguments in degrees) y = sin x, y = cos x and y = tan x for angles of any size

Tier: This item is set in standard type: all students develop confidence and competence with it. “simple cubic functions, the reciprocal function y = 1/x with x ≠ 0” is underlined; the exponential-function and trigonometric-function clauses are bold (Higher tier only).
