WebDiscrete Mathematics MCQ (Multiple Choice Questions) with introduction, sets theory, types of sets, set operations, algebra of sets, multisets, induction, relations, functions and algorithms etc. Webdiscrete mathematics, as, for instance, when we analyze the number of steps a procedure uses to sort a list of numbers into increasing order. 2.1 Sets Introduction In this section, we study the fundamental discrete structure on which all other discrete structures are built, namely, the set. Sets are used to group objects together.

In discrete mathematics, objects studied include integers, graphs, and logic statements”. Discrete mathematics studies objects that are mostly countable sets, such as integers, finite …
WebA function f: A → B is said to be one-to-one if f(x1) = f(x2) ⇒ x1 = x2 for all elements x1, x2 ∈ A. A one-to-one function is also called an injection, and we call a function injective if it is one-to-one. A function that is not one-to-one is referred to as many-to-one. WebDiscrete Mathematics Relations - Whenever sets are being discussed, the relationship between the elements of the sets is the next thing that comes up. Relations may exist between objects of the same set or between objects of two or more sets.

WebOne-One Into Functions: Let f: X → Y. The function f is called one-one into function if different elements of X have different unique images of Y. Example: Consider, X = {k, l, m} Y = {1, 2, 3, 4} and f: X → Y such that f = { (k, 1), (l, 3), (m, 4)} The function f is a one-one into function 6. Many-One Functions: Let f: X → Y.

Example 4.1. 1 Show that f ( x) = x 2 + 3 x − 2 is O ( x 3). Solution We notice that as long as x > 1, x 2 ≤ x 3 and 3 x − 2 ≤ x 3. Therefore, when x > 1, we have that f ( x) = x 2 + 3 x − 2 ≤ 2 x 3.
