given the function defined in the table below, find the average rate of char of the function over the interval 18 ≤ x ≤ 36. x f(x) 0 13 9 25 18 37 27 49 36 61
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, $a = 18$, $b = 36$, $f(a)=f(18) = 37$, and $f(b)=f(36)=61$.
Step2: Substitute values into formula
$\frac{f(36)-f(18)}{36 - 18}=\frac{61 - 37}{36 - 18}$.
Step3: Calculate the numerator and denominator
The numerator is $61-37 = 24$, and the denominator is $36 - 18=18$. So we have $\frac{24}{18}=\frac{4}{3}$.
Answer:
$\frac{4}{3}$
