the graph of a function h is shown below. use the graph of the function to find its average rate of change from x = 1 to x = 4. simplify your answer as much as possible.
Answer
Explanation:
Step1: Recall rate - of - change formula
The average rate of change of a function $y = h(x)$ from $x=a$ to $x = b$ is $\frac{h(b)-h(a)}{b - a}$. Here, $a = 1$, $b = 4$.
Step2: Determine function values from graph
From the graph, when $x = 1$, $h(1)=4$; when $x = 4$, $h(4)=16$.
Step3: Calculate rate of change
Substitute into the formula: $\frac{h(4)-h(1)}{4 - 1}=\frac{16 - 4}{3}$.
Step4: Simplify the result
$\frac{16 - 4}{3}=\frac{12}{3}=4$.
Answer:
4
