Answer:
.
Step-by-step explanation:
Over this interval, the change in the value of this function is:
.
The corresponding change in the value of
:
.
The average rate of change of function
over this interval is equal to the change in the function value divided by the corresponding change in
:
.
Thus, the average rate of change of
over the interval
would be
.
