Year 13/A2 Pure Chapter 2.7 (Functions)

This lesson details how to combine multiple transformations on a function. This can be especially tricky if we don't remember the correct order of operations; as such, the ordering of operations is a focus in this video, which I try to make explicit as I can.
This lesson is meant as preparation for Exercise 2G, page 51 of the Pearson Edexcel Pure Mathematics Year 2/A2 Textbook.
