Composite and Inverse Functions Revision Videos

These functions are difficult! But don't worry, we've found some great videos on this topic to help you to understand it better.

Inverse functions

On this video, Nancy shows us a technique for finding the inverse of a function. Thanks Nancy.

Composite functions

Composite functions are actually two functions together. Once you know which one to do first then they are not too difficult. Here's Simon Deacon to explain it a little more.

Here's Simon again with a harder example.

A third perspective from Simon Deakin, please watch the two videos above before moving onto this one!
