MATSEC AM Pure Mathematics Complete Prep Course — Lesson 40: Inverse functions

This lesson shows candidates when an inverse function exists, why a domain must be restricted to make a function one-one, and how to find f inverse by setting y equal to f of x, making x the subject and swapping letters. It covers stating the domain and range of the inverse, the verification property, reflection in the line y equals x, completing the square before restricting a quadratic, and the reversed order of a composite inverse.
