Which sets of points represents a function?
A) (4,2),(4,-2),(2,5),(2,-5)
B) (-3,9),(-2,4),(0,0),(-2,4)
C) (-3,7),(3,7),(7,3),(-7,-3)
D) (3,0),(0,6),(1,5),(0,0)

C) (-3,7),(3,7),(7,3),(-7,-3)

Step-by-step explanation:

A function has no x-values repeating in a relation.

C has no x-values that are repeating in the relation, so it is considered a function.

A, B, and D, all have repeating x-values in the relation, therefore they are not functions.

C should be the correct answer.
