Use the graph of the function $f(x)$ to place each point at the specified coordinates. You will get a message when the points are placed correctly. Point $A$ at $(7,f(7))\text{,}$ Point $B$ at $(2,f(2))$ and Point $C$ at $(-8,f(-8))\text{.}$

1. Use the graph to approximate values for the following outputs:
   $f(7) \approx$
   $f(2) \approx$
2. What is the change in the output as we move from point $B$ to point $A\text{?}$
   $\Delta f \approx$
3. What is the change in the input moving from point $B$ to point $A\text{?}$
   $\Delta x =$
4. What is the average rate of change between the points $A$ and $B\text{?}$
   $\frac{\Delta f}{\Delta x} \approx$.
