(a) Recall that two sets have the same cardinality if there is a bijection between them and that Z is the set of all integers. Give an example of a bijection f: Z+Z which is different from the identity function. (b) For the following sets A prove that A has the same cardinality as the positive integers Z+ i. A= {r eZ+By Z r = y²} ii. A=Z 1.
