The resource is for KS4 students.

This resource is a course in functions, consisting of lesson presentations for 5 lessons and a worksheet to print out for the fifth lesson. The lessons are ordered from 1 to 5.

Lesson 1 is an introduction to functions including values for which the function is not defined.

Lesson 2 explores combining functions and emphasises the differences between fg(x), gf(x), f(x)g(x), f(x)+g(x) and f(x) - g(x).

Lesson 3 involves finding the single equivalent function to two combined functions.

Lesson 4 studies solving equations involving functions.

Lesson 5 covers finding inverse functions.
