net change=$5$ average rate of change =$\frac{5}{4}$

#### Work Step by Step

We are asked to find the net change and average rate of change between $x=2$ and $x=6$. Using the graph, we see that $f(2)=2$ and $f(6)=7$. Thus we have: net change=$f(6)-f(2)=7-2=5$ average rate of change =$\frac{f(6)-f(2)}{6-2}=\frac{5}{4}$
