Answer
Answer:
3
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, $a = 1$, $b = 4$, $f(a)=f(1) = 20$, and $f(b)=f(4)=29$.
Step2: Substitute values into formula
$\frac{f(4)-f(1)}{4 - 1}=\frac{29 - 20}{3}$
Step3: Simplify the expression
$\frac{9}{3}=3$
