Question

Using the graph below, calculate the average rate of change for f(x) from x = 2 to x = 6.

Answer 1

Can you find the corresponding values of y for these 2 points?

Answer 2

when x = 2, y = 2
when x = 6, y = 6

Answer 3

Average rate of change=(yfinal-yinitial)/(xfinal-xinitial)

Answer 4

Plug in and get your answer.

Answer 5

x = 1 ?

Answer 6

xfinal=6 xinitial=2
Similarly for y.

Answer 7

6 - 2 = 4 / 6 - 2 = 4
4/4
1

Answer 8

Yeah the average rate ie slope is 1. x=1 is not the right way to say that.

Answer 9

thats how my choices come out ;/

Answer 10

Maybe they meant average rate.

Answer 11

yea
