1. find the inverse function of y = -3x + 8
2. find the inverse function of y = 3/5x - 12

Question 1:

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

To do this we follow the steps below:

We exchange the variables:

We clear the value of the variable "y":

We change y for

The inverse of the given function is
