Question

What is the inverse of the function f(x) = 4x + 8?

A. h(x) = one-quarterx – 2
B. h(x) = one-quarterx + 2
C. h(x) = one-halfx – 2
D. h(x) = one-halfx + 2

Answer 1

Sorry it said i was typing but i was afk but

My math is.....

The function:

f(x) = 4x+8

rewrite the function with y=f(x)

y=4x+8

Now we have to solve for x so,

y-8 = 4x

2= y-8/4

x=y/4-2

Now change the variables

y=x/4

Last we rewrite the function h(x) = y

h(x) = x/4 -2

So, the inverse function is h(x) = x/4-2

That should be right.
