Question

I need help someone please

Answer 1

Answer: $\frac{6}{2}$

Step-by-step explanation:

1. Use this $\frac{f(b)-f(a)}{b-a}$ to find the average rate of change

2. Average rate of change = $\frac{f(8)-f(6)}{8-6}$

3. $f(8) = - 4$ and $f(6) = -10$ (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like$\frac{-4-(-10)}{8-6}$

6. Solve $\frac{6}{2}$
