Which equation below represents the inverse function

Given function is

Or,

First step is to find the inverse is switch a and b. Therefore, the above equation will be:

b = 5*(a + 7) By simplifying.

b = 5a + 35

Next step is to solve the equation for a to get the inverse of a (b). So, subtract 35 from each sides to isolate a. Hence,

b - 35 = 5a

Therefore , the inverse is .

So, c is the correct choice.
