Given, Set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} Here, we know the set containing the numbers which are multiple of 3 not exceeding is {3, 6} And its computer representation is its corresponding bit string i.e. 0 0 1 0 0 1 0 0 0 0 Let A and B be two non-empty sets. A function f from A to B is set of ordered pairs with the property that for each element x ∈ A there is a unique element y ∈ B. Injective Function: A function (f : A to B) is said to be is said to be injective (or one-to-one, or 1-1) if for any x, y ∈ A, f(x) = f(y) impiles x = y. All this means is that for a function to be one-to-one every distinct element in A has a distinct image in B.     Surjective  Function: If every element b in B has a corresponding element a in A such that f(a) = b. It is not required that a is unique; The function f may map one or more elements of A to the same element of B.   Bijective Function: A fnction f from A to B is said to be bijective if it is both injective and surjective. If function is bijective, its inverse exists.
