a.
Answer to Problem 98E
The points of intersection are and
Explanation of Solution
Given Information:
The given functions are and where
Calculation:
It has been given that and the graph corresponding to the functions is given below:
From the above figure, it appears that the graphs intersect at two points. Using the intersect feature or zoom and trace feature, it is determined that the graphs intersect twice at approximately and
b.
To find out the value of for which the two graphs have one point of intersection.
