Given:
Consider the given function is:

To find:
The average rate of change of the function over the interval
.
Solution:
The average rate of change of the function f(x) over the interval [a,b] is:

We have,

At
,



At
,



Now, the average rate of change of the function f(x) over the interval
is:




Therefore, the average rate of change of the function f(x) over the interval
is -3.
