Functions
You need to be able to work with function notation confidently in your exam
Composite functions
If you apply two functions one after the other, you can write a single function which has the same effect as the two combined functions
This is called a composite function
Working it out
Order is important in composite functions
You can think of fg(x) as f(g(x))
You work out g(x) first then you use this answer as your input for f(x)
To find an algebraic expression for fg(x) you need to substitute the whole expression for g(x) for each instance of x in the expression for f(x)
