Which set of ordered pairs represents the relation shown in the graph?

• {(3, -5), (-2, 0), (2, 0), (-1, 1), (3, 5)}
• {(5, -3), (2, 0), (0, -2), (-1, 1), (-3, -5)}
• {(-5, 3), (0, -2), (2, 0), (1, -1), (3, 5)}

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.
