given the function defined in the table below, find the average rate of change, in simplest form, of the function over the interval 3 ≤ x ≤ 5. x f(x) 1 80 2 73 3 66 4 59 5 52 answer attempt 1 out of 2 submit answer

Answer

Explanation:

Step1: Recall average - rate - of - change formula

The average rate of change of a function $y = f(x)$ over the interval $[a,b]$ is $\frac{f(b)-f(a)}{b - a}$. Here, $a = 3$, $b = 5$.

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

When $a = 3$, $f(3)=66$; when $b = 5$, $f(5)=52$.

Step3: Calculate the average rate of change

Substitute into the formula: $\frac{f(5)-f(3)}{5 - 3}=\frac{52 - 66}{2}=\frac{-14}{2}=-7$.

Answer:

$-7$
