For each of the following functions, indicate whether the function has a well- defined inverse. If the inverse is well-defined, give the input/output relationship of f-1 (a) f:Z Z. f(x) = x +3 (b) f: ZZ. f(x) = 2x + 34 (C) f:R R. f(x) = 2x + 3 (d) Let A be defined to be the set {1,2,3,4,5,6,7,8} f: P(A) {0,1,2,3,4,5,6,7,8} For X CA, (X) = X]. Recall that for a finite set A, P(A) denotes the power set of A which is the set of all subsets of A
