Answer:
[-5,1] or [-4,5]
Step-by-step explanation:
Here, we want to get the intervals over which there is an average rate of change of zero for f
For this to happen, over the given interval, there will not be a change in the y-axis value
What this mean is that the y-axis value will remain the same over this given interval
for x = -5 to x = 1, we have this
for x = -4 to x = 5 , we have this
