Which set of ordered pairs does not represent a function? / { (4, 6), (9, - 2), (3, - 5), (6, 6) / }{ (4,6), (9,-2), (3,-5), (6,6) } / { (-1, - 2), (-4, 9), (8, - 9), (1, 2) / }{ (-1,-2), (-4,9), (8,-9), (1,2) } / { (-1, 9), (-7, 8), (3, - 1), (4, - 1) / }{ (-1,9), (-7,8), (3,-1), (4,-1) } / { (2, 2), (0, - 8), (2, 7), (-3, 8) / }{ (2,2), (0,-8), (2,7), (-3,8) }
