Answer: A and D

Explanation:

The function is positive when the graph is above the x-axis.

in the image we can see that the graph is above in between the points:

x = - 5 and x = 0, then goes bellow, and then comes up again at x = 3.5 and the graph ends at x = 4.

Then the regions where the function is positive are:

-5 < x < 0 and 3.5 < x < 4

Then the correct options are:

A and D
