State which of the following sets of ordered pairs represent a function.Set A: (5, 2), (4, 3), (3, 4), (2, 5)Set B: (-1, -6), (0, 2), (1, 2), (3, 6)Set C: (2, 1), (4, 2), (2, 3), (8, 4)

A set of ordered pairs represents a function when each input (the first number) is paired with exactly one output. In Set A and Set B, no first number repeats, so both sets represent functions. In Set C, the input 2 is paired with both 1 and 3, so it is not a function. Therefore, the correct choice is Set A and Set B.
