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

An ordered-pair relation is a function when each input (the first coordinate) is paired with exactly one output. Set A and Set B each have distinct first coordinates, so both are functions. Set C uses the input 2 twice, paired with 1 and 3, so it is not a function. Therefore, the correct choice is “Both Set A and Set B.”
