Question

Find the inverse of each function (show work please)

Answer 1

To find the inverse function of a function, you rearrange for the x term (could be some other letter) and then swap the function and the x at the end. For example,

`g(x)=15x-10 \Rightarrow x=(g(x)+10)/(15)` and so,

`g^(-1)(x) = (x+10)/(15).`

For part 3 we have

`h(x)=(x-12)/(4) \Rightarrow x=4h(x)+12` and hence,

`h^(-1)(x)=4x+12=4(x+3)`

Can you do part 4 on your own?
