Question

Use the graph below for this question: graph of parabola going through negative 3, negative 1 and 5, negative 1. What is the average rate of change from x = −3 to x = 5?

Answer 1

Here the points are(-3,-1) and (5,-1)

To find the average rate of change, we have to use the following formula .

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Here x1 =-3, y1=-1, x2=5,y2=-1

So we get

Average rate of change=

$\frac{-1+1}{5+3} = 0$

So the average rate of change from x=-3 to x=5 is 0
