Solve for the inverse of: f(x)=1/8(x+1)^3

or

Step-by-step explanation:

To find the inverse, you switch y with x and x with y. Then, you solve for y.

         [switch y with x and x with y]

         [multiply both sides by 8]

          [cube both sides]

            [subtract both sides by 1]

or

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
