Compare the rates of change for the functions represented below.

Which statements about the rates of change for Function C and Function D are true? Select **all** true statements.

A

Function D has a greater rate of change because it has a positive rate of change, and function C does not.

B

Function C has a greater rate of change because it has a positive rate of change, and function D does not.

C

Functions C and D have the same positive rate of change.

D

Functions C and D have the same negative rate of change.

E

The y-intercept of function D is equal to the y-intercept of function C.

F

The y-value when x = 0 for function C is greater than the y-value when x = 0 for Function D.
