Answer: A and D
Step-by-step 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
