14. Which two sets of ordered pairs are functions?
A
(-3,-1), (-3,0), (-3,3), (-3,5)
B (-2, -1), (-1,0), (0,0), (2,1)
C (-1,-1), (-1,0), (0,0), (0,1)
D (0,0), (3,0), (3,3), (4,0)
E (1, 1), (2,2), (3,3), (4,4)

Answer :

A is NOT a function because the x value input (-3) has multiple y value outputs (-1, 0, 3, 5).

B is a function because each input has only one output.

C is NOT a function because the inputs (-1 and 0) both have more than one output.

D is NOT a function because the input 3 has more than one output.

E is a function because each input has only one output.
