Question

The function P(m) below relates the amount of time (measured in minutes)
Steve spent on his homework and the number of problems completed.
It takes as input the number of minutes worked and returns as output the
number of problems completed.
P(m) = m/6 +9
Which equation below represents the inverse function Mp), which takes the
number of problems completed as input and returns the number of minutes
worked?

Answer 1

Do you know how to find \[f^{-1}(x)\]

Let y=P(x). Switch the y and the x. Then solve for y. You'll get your inverse function.
