given the function defined in the table below, find the average rate of change, in simplest form, of the function over the interval 5 ≤ x ≤ 6. x f(x) 3 2 4 6 5 18 6 54 answer
Answer
Explanation:
Step1: Recall average - rate - of - change formula
The average rate of change of a function $y = f(x)$ over the interval $a\leq x\leq b$ is $\frac{f(b)-f(a)}{b - a}$. Here, $a = 5$, $b = 6$, $f(a)=f(5) = 18$, and $f(b)=f(6)=54$.
Step2: Substitute values into formula
$\frac{f(6)-f(5)}{6 - 5}=\frac{54 - 18}{1}$.
Step3: Simplify the expression
$\frac{36}{1}=36$.
Answer:
36
