We are given the following function:
We are asked to determine the rate of change of the function in the interval:
To do that we will use the following formula:
Where "a" and "b" are the extreme values of the function. -
We have that "a = -8" and "b = 0". Now, we substitute the value of "a" in the function:
Now, we substitute the value of "b":
Now, we substitute the values in the formula for the rate of change:
Therefore, the rate of change is -1
