Find the inverse function of g(x) = 2x + 4. g -1(x) = 4x + 2 g -1(x) = 2x + g -1(x) = x - 2 g -1(x) = 2x - 4

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

Replace g(x) with y:

We exchange the variables:

We solve for "y":

We subtract 4 on both sides of the equation:

We divide between 2 on both sides of the equation:

We change y by :
