Question

For each table of values, select weather the table represents a linear or exponential relationship

Answer 1

Linear would be if the change between the x and y's are similar:

Function A:

9.252 - 6.083 = 3.169

14.07 - 9.252 = 4.818

21.4 - 14.07 = 7.33

The differences are different so it is exponential.

Function B

14-7 = 7

21 - 14 = 7

28 - 21 = 7

The differences are the same so this is linear.

Function C

4-16 = -12

1-4 = -3

0.25 - 1 = -0.75

The differences are different so this is exponential.
