Estimate the average rate of change between x = 0 and x = 2 for the function shown.

a) 6
b) 7
c) 12
d) 24

A ) 6

Step-by-step explanation:

The formula for Average rate of change is:

Aroc = change in y / change in x.

Aroc = y2-y1 / x2 - x1

The first point will be (x1,y1), and second will be (x2,y2).

x1 is 0, and when the x value is at 0, the y value is at -7, so the coordinate point is (0, -7).

For the second point, x = 2, and the corresponding y value is 5. So you just simpliy plug everything into the formula to find AROC:

=  5 - (-7) / 2 - 0

= 12 / 2

= 6

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
