Question

Find the average rate of change of a function that contains the points (-2,3) and (2,5).

Answer 1

average rate of change is total change in y divided by total change in x...

r=(5-3)/(2--2)

r=2/4

r=1/2

Answer 2

Answer: 0.5

Step-by-step explanation:

We know that the  average rate of change of a function that contains the points (a,b) to (c,d) is given by :-

$\dfrac{d-b}{c-a}$

Then, the  average rate of change of a function that contains the points (-2,3) and (2,5)will be:-

$\dfrac{5-3}{2-(-2)}=\dfrac{2}{2+2}\\\\=\dfrac{2}{4}=0.5$

Hence, the average rate of change of a function that contains the points (-2,3) and (2,5). = 0.5
