Functions and graphs: Function machines and composition of functions
Composing functions
Determine for \(f(x)=3 x+4\) and \(g(x)=3 x-4\) the function rule for the following composed functions in simple expanded forms.
| \(f\bigl(f(x)\bigr)={}\;\) |
| \(f\bigl(g(x)\bigr)={}\;\) |
| \(g\bigl(f(x)\bigr)={}\;\) |
| \(g\bigl(g(x)\bigr)={}\;\) |
