# Can we compose two simple functions? Add to your resource collection Remove from your resource collection Add notes to this resource View your notes for this resource

Ref: R9527

## Suggestion

Let $f(x)=x+1\qquad\text{and}\qquad g(x)=2x.$

1. Let $m\geq0$ be an integer. How many different ways of combining the functions $f$ and $g$ are there that result in the function $4x+4m$?

Can we use part (iii) of this question here? How many times do we need to do $g$? And $f$?
