Answer

Explanation:

Step1: Recall the average - rate - of - change formula

The formula for the average rate of change of a function $y = g(x)$ on the interval $[a,b]$ is $\frac{g(b)-g(a)}{b - a}$. Here, $a=-2$ and $b = 4$.

Step2: Identify $g(a)$ and $g(b)$ from the table

From the table, when $x=-2$, $g(-2)=11$, and when $x = 4$, $g(4)=2$.

Step3: Calculate the average rate of change

Substitute $a=-2$, $b = 4$, $g(-2)=11$, and $g(4)=2$ into the formula: $\frac{g(4)-g(-2)}{4-(-2)}=\frac{2 - 11}{4 + 2}=\frac{-9}{6}=-\frac{3}{2}$.

Answer:

$-\frac{3}{2}$
