Answer

8 Explanation 1. Identify the function values Calculate g(2) = 2^2 = 4 and g(6) = 6^2 = 36. 2. Apply the average rate of change formula Use the formula **\frac{g(b) - g(a)}{b - a}** where a = 2 and b = 6. Substitute to get \frac{36 - 4}{6 - 2}. 3. Simplify the expression Simplify \frac{32}{4} = 8.

Explanation

1. Identify the function values<br /> Calculate $g(2) = 2^2 = 4$ and $g(6) = 6^2 = 36$.<br /><br />2. Apply the average rate of change formula<br /> Use the formula **$\frac{g(b) - g(a)}{b - a}$** where $a = 2$ and $b = 6$. Substitute to get $\frac{36 - 4}{6 - 2}$.<br /><br />3. Simplify the expression<br /> Simplify $\frac{32}{4} = 8$.
