a. find the point P where the line segment between and crosses the graph of .
b. find the distance from to P and the distance from to P.
c. find the slope of the line segment between and .
d. Do your results support the relationships that must be true for the graph of a function and its inverse?
2. No, the inverse of is not a function because the graph of does not pass the horizontal line test.
(Alternative answer): No, the inverse of is not a function because is not one-to one on its domain.
