2.57 Inverse Functions Higher GCSE PowerPoint Lesson

In this 22-slide lesson, students will be introduced to inverse functions, learning how to find the inverse of a given function by rearranging algebraic expressions and using function notation such as f−1(x). They will explore how inverse functions reverse the input-output process and practise rearranging harder formulae. Through examples and practice, students will find inverse functions for linear and simple algebraic functions and use them to solve equations involving inverse notation. The lesson builds on prior knowledge of solving equations and function substitution, helping students understand how to interpret and work with inverse relationships algebraically.

This lesson is for the higher tier only.

The lesson includes:

• Clear, guided examples

• Discussion opportunities from Think, Pair, Share

• Mini whiteboard section to check understanding and clarify misconceptions

• Two structured tasks to practise key skills

• Challenge activity to extend and deepen learning

Perfect for engaging learners while reinforcing essential algebra concepts.
