Given the function defined in the table below, find the average rate of change, insimplest form, of the function over the interv
Reil [10]

To find the average rate of change in a interval

a\leq x\leq b

We use the following formula:

\frac{f(b)-f(a)}{b-a}

Applying this to our interval

6\leq x\leq15

We have the following rate of change:

\frac{f(15)-f(6)}{15-6}=\frac{107-53}{9}=\frac{54}{9}=6

We have an average rate of change equals to 6.
