Expert Solution
Step 1
We are given the following graph of .
We know the following.
is increasing if derivative ,
is decreasing if derivative ,
is constant if derivative .
For (A),
We can observe that for the intervals (-4,1) and (4, 5) we have .
So, the function is increasing on (-4,1) U (4, 5).
For (B),
We can observe that for the intervals (-5,-3) and (0,4) we have .
So, the function is decreasing on (-5,-3) U (0,4).
