Using it's concept, it is found that the average rate of change of the function over the interval is of 0.
It is given by the change in the output divided by the change in the input.
In this problem, in the interval from x = -2 to x = 0, the input remains constant at - 1, hence:
[tex]r = \frac{-1 - (-1)}{0 - (-2)} = 0[/tex]
The average rate of change of the function over the interval is of 0.
