Need asap which set of ordered pairs represents a function? {(0, 1), (1, 3), (1, 5), (2, 6)} {(0, 0), (1, 2), (2, 4), (3, 4)} {(0, 1), (1, 2), (2, 3), (2, 4)} {(0, 0), (0, 2), (2, 2), (2, 4)}

A function is a special relationship where each input has a single output.

{(0, 1), (1, 3), (1, 5), (2, 6)} NOT because for x = 1 we have y = 3 and y = 5

{(0, 0), (1, 2), (2, 4), (3, 4)} YES

{(0, 1), (1, 2), (2, 3), (2, 4)} NOT because for x = 2 we have y = 3 and y = 4

{(0, 0), (0, 2), (2, 2), (2, 4)} NOT because for x = 0 we have y = 0 and y = 2

and for x = 2 we have y = 2 and y = 4.

the answer is 31.27mph
