Functions (Composite and Inverse) | 40 Worked Examples | Edexcel GCSE Higher Maths

40 progressive Edexcel GCSE Higher (1MA1) function questions with full mark-scheme style worked solutions. Every line is explained and every mark is annotated at the exact point it would be awarded.

What’s inside:
Easy: evaluating f(a), substituting negatives and fractions, and solving f(x) = k.
Medium: composite functions fg(x) and gf(x) both as numbers and as expressions, and finding inverse functions of linear rules.
Hard: solving composite equations, ff(x), inverses of fractional and quadratic functions with a restricted domain, showing fg(x) is not gf(x), and fixed points.

Every solution breaks the work down one step at a time, with the reasoning spelled out in plain English and the order of composite functions made explicit. Typeset in LaTeX for clean mathematical notation.

Ideal for: Year 10 and 11 students sitting Edexcel GCSE Higher Mathematics (1MA1), plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
