Which function has the greatest constant of variation? A x 8 9 10 11 y 20 22.5 25 27.5 B x 1 2 3 4 y 3.2 6.4 9.6 12.8

b the answer is b

Answer : B x 1 2 3 4 y 3.2 6.4 9.6 12.8

WE analyze the first option A

x - - y - - Difference

8 - - 20

9 - - 22.5 - - 2.5

10 - - 25 - - 2.5

11 - - 27.5 - - 2.5

From the first function we can see there is a constant difference of 2.5.

We analyze the second option B

x - - y - - Difference

1 - - 3.2

2 - - 6.4 - - 3.2

3 - - 9.6 - - 3.2

48 - - 12.8 - - 3.2

From the second function we can see there is a constant difference of 3.2

3.2 is the greatest

So second function B has the greatest constant of variation.
