Of these three linear functions represented below, what has the greatest rate of change?

-Function 1: y=2x+6

-Function 2: (this is a table)

x|y

-1|3

1|15

2|21

-Function 3: a number y is less than half a number x.

A) Function 3 has greatest rate of change

B) Function 2 has the greatest rate of change

C) Function 1 has the greatest rate of change

D) All three functions have the same rate of change

*would like the steps to solve this also.
