Using it's concept, the average rate of change of the function over the interval 10 < x < 22 is given by:
[tex]r = \frac{f(22) - f(10)}{12}[/tex]
It is given by the change in the output divided by the change in input.
Over the interval 10 < x < 22, the outputs are f(10) and f(22), hence the rate of change is given by:
[tex]r = \frac{f(22) - f(10)}{12}[/tex]
