Let sets A, B, and C be the following, . A = (1,2,3,5) . B = (1,2,3, 4,5, 6, 7,8,9, 10) . C = (2,3,5,7,11 ) Answer the following statements, . How many function from A to A are reflexive? . How many functions from B to B are injective but not surjective (Hint: consider pigeon hole principle)? . How many functions from B to B would be a symmetric relation (opposed to a symmetric function)
