Let A ={9, 10, 11, 12, 13) and f: A-> N be defined by f(n)-highest prime factor of n, 33. 1) (13) 3) (11, 13 13, 5, 11, 13 4) [2, 3, 5, 11)

List two most common STDs.

R is a relation from {11, 12, 13} to {8, 10, 12} defined by y=x-3 . Then, R^(-1) is (a) {(8, 11), (10, 13)} (b) {(11, 8), (13, 10)} (c) {(10, 13), (8, 11), (8, 10)} (d) none of these
