Explanation:
The question is incomplete as the function is not given. However, the following explanation will guide you.
The average rate of change is calculated using;
![A = (f(b) - f(a))/(b - a)](https://img.qammunity.org/2021/formulas/mathematics/high-school/sc0d6140jqgm71avwxpd3a2pcd3s44r6st.png)
Where
![(a,b) = (-1,5)](https://img.qammunity.org/2021/formulas/mathematics/high-school/v29kc4slrleny83ae1r8efe57fp4gbuxpi.png)
Take for instance;
The function is:
![f(x) = 2x](https://img.qammunity.org/2021/formulas/mathematics/high-school/pfyi7dxuykqfq8d0tqaqepva45e6auci6g.png)
We have to solve for f(-1) and f(5);
i.e.
![f(-1) = 2 * -1 -2](https://img.qammunity.org/2021/formulas/mathematics/high-school/d48z97pcckw8yus143b1tuuozccu99khgl.png)
![f(5) = 2 * 5 = 10](https://img.qammunity.org/2021/formulas/mathematics/high-school/px7ekxgggv3zq1p2douqpoobzeein7k4ud.png)
Substitute -1 for a and 5 for b
![A = (f(b) - f(a))/(b - a)](https://img.qammunity.org/2021/formulas/mathematics/high-school/sc0d6140jqgm71avwxpd3a2pcd3s44r6st.png)
![A = (f(5) - f(-1))/(5 - (-1))](https://img.qammunity.org/2021/formulas/mathematics/high-school/ndqc9fdl5ly4gkhpxlr5akh9fwem0mqr64.png)
![A = (f(5) - f(-1))/(5 +1))](https://img.qammunity.org/2021/formulas/mathematics/high-school/1t0915polun7s240pn4s3rbp34iy5y6d4t.png)
![A = (f(5) - f(-1))/(6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/cm6ejc1l8xk4yxwcupa1awmfauna26e1gw.png)
Substitute values for f(5) and f(-1)
![A = (10 - (-2))/(6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/99p4ae3lnimfkfphqbylo2enyq7qcsfjiz.png)
![A = (10 +2)/(6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/s02hdl5y01sxmepietajze152s00w5uiy4.png)
![A = (12)/(6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/afq1845cnnev8yciyvhpxg6ehdceu6xnhz.png)
![A = 2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/mh2cdjdqa56pfmkbpbnysjvd7jl7kz0t3a.png)
