the graph shows the side view of a waterslide. dimensions are in feet. two points on slide: (0, 80), (5, 40) complete what is the average rate of change from x = 0 to x = 5? done
Answer
Explanation:
Step1: Recall rate - of - change formula
The formula for the average rate of change of a function $y = f(x)$ from $x = a$ to $x = b$ is $\frac{f(b)-f(a)}{b - a}$. Here, $a = 0$, $b = 5$, $f(0)=80$, and $f(5)=40$.
Step2: Substitute values into formula
$\frac{f(5)-f(0)}{5 - 0}=\frac{40 - 80}{5}$.
Step3: Calculate the result
$\frac{40 - 80}{5}=\frac{-40}{5}=-8$.
Answer:
$-8$
