Which set of ordered pairs does not represent a function? a) (0, 1), (2, 2), (4, 8), (-2, 7), (5, 8) b) (0, 1), (2, 2), (4, 8), (2, 7), (5, 8), (7, 9) c) (-3, 6), (2, 7), (0, 5), (1, 5), (4, 9), (5, 4) d) (-4, 2), (-3, 2), (-2, 2), (-1, 2), (0, 2), (1, 2) which set of points is a function? a) {(0,,,6)} b) {(1,,,2)} c) {(1,,,6)} d) {(2,,,6)}

A set of ordered pairs does NOT represent a function when an input(x value) has multiple outputs(y value). The input can only have one output.

For the first one the answer is B because when x is 2, it has multiple y values. (2, 2) and (2,7)

For the second one the answer is B because A, C, and D have inputs(x values) that have multiple outputs(y values)
