Determine which relation is a function. A. {(–4, 3), (–2, 3), (–1, 2), (2, 5), (3, 2)} B. {(–4, 1), (–2, 3), (–2, 1), (–1, 5), (3, 2)} C. {(–4, 1), (–2, 3), (–1, 2), (3, 5), (3, 2)} D. {(–4, 1), (–2, 3), (–1, 1), (–1, 5), (3, 2)}

Respuesta :

A would be correct because the others fail. If you have the same x value on more than one ordered pair, it is not a function...B (-2,3) and (-2,1)...C (3,5) and (3,2).....and D (-1,1) and (-1,5)
