Let A = {1, 3, 5, 6, 7, 9, 10, 12} and B = {1, 2, 3, 5, 7, 8, 9, 11, 12}. Consider the following function f: A B defined by: f(1) = 12, f(3) = 11, ƒ(5) = 8, ƒ(6) = 7, ƒ(7) = 5, ƒ(9) = 1, ƒ(10) = 9, ƒ(12) = 2. You are required to determine whether the function f is an injection, surjection, bijection. To obtain marks you will need to make a correct selection on all of these. • Function f is an injection: Select • Function f is a surjection: Select • Function f is a bijection: Select
