Question

Which set of ordered pairs does not represent a function? A. {(10, 1), (–2, –16), (–6, 7), (5, 1), (8, –16), (–11, 9)} B. {(–2, –6), (–8, 13), (–7, –4), (–2, –8), (11, 8)} C. {(15, –3), (–6, 4), (–3, 0), (–1, 16)} D. {(6, 2), (–12, –16), (–6, 10), (20, 2)}

Answer 1

B. {(–2, –6), (–8, 13), (–7, –4), (–2, –8), (11, 8)}
