c.
To state : that whether the inverse relation is an inverse function or not.
c.

Answer to Problem 110E
yes, the inverse relation is an inverse function.
Explanation of Solution
Given information :
The function is
from the above graph shown in part (b) it can be observed that the graph of inverse function havenot any vertical line that intercept the graph more than one time, so the inverse function satisfy the vertical test.
So inverse relation isan inverse function or not.
