If G (x) = 3x + 1, then G^-1 (1) is

You'll need to find the inverse function of G (x) first. Are you familiar with that process? Find the inverse, and then let x=1.

Step 1: Replace "G (x) " with y.

Step 2: Solve the resulting equation for x.

Step 3: Replace x with y and y with x.

-1

Step 4: Replace this "y" with G (x).

Now replace "x" with "1".
