Answer 1

What's the question?

Answer 2

if f(x)=4x-8, what is f^-1(x)?

Answer 3

Let's do the same thing we did before.

Answer 4

Answer 5

To find the inverse of any function. You start by replace the x and y variables.
So in this case, You have the original function f(x)=4x-8, f(x) is also y
So y=4x-8
Start by replacing x with y and y with x

So x=4y-8
Now solve the equation for y.

Answer 6

So x=4y-8
Subtract the 4y from the right side and left side
You have x-4y=-8
now subtract the x from both sides
-4y=-x-8
Divide the whole equation by -4
So y=...........

Answer 7

would it be C?

Answer 8

A) f^-1(x)=1/2x+2
B) f^-1(x)=1/4x+2
C) f^-1(x)=1/2x+4
