What is a Relation?
For any two non-empty sets A and B, we define the relation R as the subset of the Cartesian product of A × B where each member of set A is related to the member of set B through some unique rule.
We defined relation as,
R = {(x,y): x ∈ A and y ∈ B}
Example: The relation R = {(1,1), (2,4), (3,9)} and it is represented using {}.
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.
