Question

What is the inverse of the function below

Answer 1

it would be letter d because you switch everything when it says inverse

Answer 2

`f^(-1)=4(x+2)`

Explanation:

`f(x)=(x)/(4) -2`

To find inverse function , replace f(x) with y

`y=(x)/(4) -2`

Swap the variables x and y

`x=(y)/(4) -2`, nbw we solve for y

Add 2 on both sides

`x+2=(y)/(4)`

Now to eliminate 4, we multiply 4 on both sides

`y=4(x+2)`

Replace y with f^-1

`f^(-1)=4(x+2)`
