Which statement is true about the relation {(-2, 4), (4, 2), (2, 4), -4, 2)}?

• The relation is NOT a function because all the y-values are not different.
• The relation is NOT a function because all the x-values are not different.
• The relation is a function because the y-values are different.
• The relation is a function because all the x-values are different.
