If f(x) = 4x + 7, which of the following is the inverse of f(x)? o a. f-'(x) = 4x - 7 o b. f'() = *=4 c. fgx) = 7 - 4x o d. f"(x) = *z?

For this case we must find the inverse of the following function:

For it:

Replace f (x) with y:

We exchange the variables:

We solve for y:

We subtract 7 on both sides of the equation:

We divide between 4 on both sides of the equation:

Finally, we change y by:

answer: about 22.67
