Given the sets A = {-3, -2, -1, 0, 1, 3 } and B = {t, w, x, y, z}, indicate which of the following relation is a function from A to B. O a) {(-2, a), (3, a), (0, y), (2, w), (1, t) } Ob) { (0, ac), (-3, w), (0, y), (1, t), (-2, 2) } Och {(-2, a), (3, a), (0, y), (1, t) } O d) { (3, a), (1, ac), (0, w), (2, t) }
