(1 point) Let A = {a, b, c, d} and B = {1, 2, 3, 4}. Define f : B - Bby f(1) = 2, f(2) = 1, f(3) = 4, and f(4) = 3. Also, define g : A - B by g(a) = 1, g(b) = 2, g(c) = 3, g(d) = 4. Compute glo fog. Answer: g lo fog : A - A is given by (g lo fog)(a) = (g lo fog)(b) = (g lo fog)(c) = (g lo fog)(d) =(1 point) Let f : R - IR be given by f(x) = 4x + 5. (a) Compute f-1. Answer: f-1 : R - R is given by f-1 (x) = (Enter a simple formula for f-1(x) in terms of .) (b) Compute the following: (f-1 o f) (13) =
