X = {1,2,3,4} Y = {a, b, c, d] Given above sets, choose if each of the following statement is True or False. True False {(1, a), (2, b), (3, c), (3, d)} is a function from X to Y. {(1, b), (2, d), (3, a),(4, c) } is an invertible function from X to Y. {(a, 2), (6,3), (c, 1), (d, 2)} is an onto function from Y to X. {(a, 1), (1, b), (c, 3), (4, d)} is a one-to-one function from Y to X
