Question

Find the average rate of change of the function

Answer 1

The average rate of change from an interval from $x_1$ to $x_2$ is the change in the value of the function divided by the change in x.

$\dfrac{f(x_2)-f(x_1)}{x_2-x_1}$

Let's find the values of $f(x_1)$ and $f(x_2)$

$f(x_1)=7(2)=14$
$f(x_2)=7(0)=0$

Average rate of change $=\dfrac{f(x_2)-f(x_1)}{x_2-x_1}$

$= \dfrac{14-0}{2-0}=\boxed{7}$

Your answer is 7. I hope this helps! :)
