Topics Covered in Exercise 2.2 Class 11 Mathematics Questions

Ex 2.2 class 11 maths chapter 2 is completely about relations and its properties. You will learn all the concepts in detail related to this topic provided here.

1. Relations - A relation R from a set A to a set B is a subset of the cartesian product A × B obtained by describing a relationship between the first element x and the second element y of the ordered pairs in A × B.

Some Other Fact About Relations

1. A relation R from a non-empty set A to a non-empty set B is a subset of the cartesian product A × B. The subset is derived by describing a relationship between the first element and the second element of the ordered pairs in A × B. The second element is called the image of the first element.
2. The set of all first elements of the ordered pairs in a relation R from a set A to a set B is called the domain of the relation R. 
3. The set of all second elements in a relation R from a set A to a set B is called the range of the relation R. The whole set B is called the codomain of the relation R. Note that range ⊂ codomain.

Properties of Relations

(i) A relation may be represented algebraically either by the Roster method or by the Set-builder method.

(ii) An arrow diagram is a visual representation of a relation.

(iii) A relation R from A to A is also stated as a relation on A.
