Answer 2

`f^(-1)(x)=(1)/(4)x+3`

Explanation:

We have been given the function
`f(x)=4x-12`

Below are steps for finding the inverse of the function.

Step 1:

Replace f(x) with y

`y=4x-12`

Step 2:

Interchange x and y

`x=4y-12`

Step 3:

Solve for y

`x+12=4y\\\\y=(1)/(4)x+3`

Step 4:

Replace y with
`f^(-1)(x)`

`f^(-1)(x)=(1)/(4)x+3`
