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

Answer:

$f^{-1}=4(x+2)$

Step-by-step explanation:

$f(x)=\frac{x}{4} -2$

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

$y=\frac{x}{4} -2$

Swap the variables x and y

$x=\frac{y}{4} -2$, nbw we solve for y

Add 2 on both sides

$x+2=\frac{y}{4}$

Now to eliminate 4, we multiply 4 on both sides

$y=4(x+2)$

Replace y with f^-1

$f^{-1}=4(x+2)$
