Reflexive Relations
A relation where each component of a set A is mapped to itself is called reflexive relation, i.e. for every x ∈ A, (a, a) ∈ R
Example: For set A = {-1, 4}. Reflexive relation is R = {(-1, -1), (4, 4), (-1, 4), (4, -1)}
Introduction to Domain and Range
To understand the concept of Domain and range of a Relation first, we have to learn about Relation. A relation is a set of rules which relates the value of one set to the value of other sets.
The domain of a relation is the set of values that we take as input and the range is the set of the values which are obtained in the form of the answers to the relation.
In this article, we will learn about the Domain and Range of Relations, its examples, and others.
