SOLUTION:

The formula for the average rate of change of a function is;

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

For f(x);

[tex]\begin{gathered} m=\frac{30-(-10)}{2-(-2)} \\ m=10 \end{gathered}[/tex]

For (x):

[tex]\begin{gathered} m=\frac{10-46}{2-(-2)}= \\ m=-9 \end{gathered}[/tex]

For h(x):

[tex]\begin{gathered} m=\frac{h(2)-h(-2)}{2-(-2)} \\ m=\frac{(-2^2-5(2)+25)-(-(-2)^2-5(-2)+25)}{2-(-2)} \\ m=-5 \end{gathered}[/tex]

From this calculation, ranking the average rateof change from least to greatest, swe have;

[tex]g(x),h(x),f(x)[/tex]
