Let a = {1, 2, 3, 4, 5} and b = {a, b, c, d}. for each of the following relations fromn a to b, answer these questions: is it a function from a to b? if it is a function from a to b, is it one-to-one? is it onto? justify.
(a) {(1, c ) ,(2, c ) ,(3, c ) ,(4, c ) ,(5, d ) }
(b) {(1, a ) ,(2, d ) ,(3, a ) ,(4, c ) }
(c) {(1, d ) ,(2, d ) ,(3, a ) ,(4, b ) ,(4, d ) ,(4, c ) } .
(d) {(1, c ) ,(2, b ) ,(3, a ) ,(4, d ) ,(5, a ) }
