A relation is a function, if and only if, the x-values do not repeat in a given set. This is an example of an ordered pair. Sets are usually denoted by capital letters A, B,C,… and elements are usually denoted by small letters a, b,c,… Then the relation R is. To determine if a relation is a function, we just need to make sure that no element has two corresponding range values. Nothing really special about it. 2.1.3 Functions A relation f from a set A to a set B is said to be function if every element of set A has one and only one image in set B. For example, y = x + 3 and y = x 2 - 1 are functions because every x-value produces a different y-value. An ordered pair, commonly known as a point, has two components which are the x and y coordinates. In this chapter, we introduce the notions of sets, relations and functions which are the basic tools of discrete mathematics. A function f from a set P to a set Q, represented as f: P-> Q, is a mapping of elements of P (domain) to elements of Y(co-domain) in such a way that each element of P is assigned to some chosen element of Q. A set is a collection of well-defined objects that contains no duplicates. Examples: x = x for any x. Relations of this sort are called reflexive. Sets, Relations and Functions.
