4. Consider the following relations R on the integers Z. For each of these relations, say whether the following statements are true or false: (i) R is reflexive; (ii) R is symmetric; (iii) R is a function; (iv) R is irreflexive. a. R= {(n, m) E Z x Z[ m = {(n,m) E Z x Z| (n is even A m is odd) V (n is odd A m is even)}. = {(n,m) E Z x Z| m = 100}. b. R= - -n}.
