Learn how to evaluate the composite of two functions, the inverse of a function and how the two relate to each other
Key Points
Composite functions are when you merge two, or more, functions
To find the composite of two functions you put one ‘inside’ the other
The inverse of a function is the reverse, or opposite, of the function
To find the inverse of a function change the subject of the formula
The composite of a function with it’s inverse cancel, leaving just ‘x’
