4 True or False. Explain briefly (you can use diagram to show, or one or two short sentences). (a) For a function f: X Y, where both domain X and codomain Y are finite sets, if f is an one-to-one function, then X|< Y . For a function f: X- Y, where both domain X and codomain Y are finite sets, if f is an surjective function function, then |X| |Y.
