Answer to Problem 20E
f is increasing on the interval [-2,3] .
Explanation of Solution
Given information: the graph provided in the question,
From the provided information, consider,
As f increases the height if the function f ( x ) also increases, thus, y-values of the points on the graph increase as the x-values increase. In the graph provided, f is increasing on the interval [-2,3]
Hence, f is increasing on the interval [-2,3] .
b.
To find: where f is decreasing.

Answer to Problem 20E
f is decreasing on the intervals [1,-2] and [3,0].
Explanation of Solution
Given information: the graph provided in the question,
From the provided information, consider,
As f decreases, the height if the function f ( x ) also decreases, thus, y-values of the points on the graph decrease as the x-values increase. In the graph provided, f is decreasing on the intervals [1,-2] and [3,0].
Hence, f is decreasing on the intervals [1,-2] and [3,0].
