Question

I. For each of the following mappings f: z →z, exhibit a right inv to mapping composition whenever one exists. a,f(x) = 2x c, f(x) = x + 2 b. f(x) 3x d. f(x)1 -x if x is even 1 if x is odd x if x is even if x is odd g, f(x) = 2x h. f(x) = x _ 1 j. f(x) = x-1x1 if x is even r1 if x is even 2x if x is odd if x is odd x +1if x is even if x is odd if x is evern n.fw-仁+1 r 2 if x is odd 2. For each of the mappings f given in Exercise 1, determine whether fhas a left inverse. Exhibit a left inverse whenever one exists.
