No, certainly not.  The slope is undefined if and when the line in question is vertical.

If F(x) = 4%-3, which of the following is the inverse of F(x)?
Brums [2.3K]

I assume you meant to type x for %.

If not, basically back-substitute at the end of the solution.

F(x) = 4x - 3

Let y = F(x)

y = 4x - 3

x = 4y - 3

x - 3 = 4y

(x - 3)/4 = y

Let y = F^(-1)x

F^(-1)x = (x - 3)/4

If you want % in your answer, just replace x for % in your answer.
