b.
Answer to Problem 8E
The y-intercept of the graph of the given function is
Explanation of Solution
Given information: The function is
Calculation:
The function is
The y-interceptis
Hence the y-intercept of the graph of the given function is
c.
To calculate: The intervals on which the graph of the given function is increasing and decreasing.
c.
Answer to Problem 8E
The function is increasing in the intervals
The function is decreasing in the intervals
Explanation of Solution
Given information: The function is
Calculation:
The function is
As it can be observed from the graph the function is
Hence, the function is increasing in the intervals
&
The function is decreasing in the intervals
