Question

Which set of ordered pairs represents a function? \{(5, -2), (0, 3), (-4, 6), (0, 5)\}{(5,−2),(0,3),(−4,6),(0,5)} \{(5, 7), (5, 6), (3, -1), (7, 4)\}{(5,7),(5,6),(3,−1),(7,4)} \{(-5, -9), (8, -4), (-4, -3), (4, -4)\}{(−5,−9),(8,−4),(−4,−3),(4,−4)} \{(-9, 6), (-2, 8), (-9, -5), (8, -6)\}{(−9,6),(−2,8),(−9,−5),(8,−6)}

Answer 1

(-5, -9), (8, -4), (-4, -3), (4, -4)

a function does not have a repeating domain or x. hope this helps.
