Expert Solution
Step 1

We are given the following graph of f'.

Advanced Math homework question answer, step 1, image 1

We know the following.

f(x) is increasing if derivative f'(x)>0,
f(x) is decreasing if derivative f'(x)<0,
f(x) is constant if derivative f'(x)=0.

For (A),

We can observe that for the intervals (-4,1) and (4, 5) we have f'(x)<0.

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 f'(x)>0.

So, the function is decreasing on (-5,-3) U (0,4).
