# NCERT Solutions Class 12 Maths Chapter 1 Relations and Functions

NCERT Solutions for Class 12 Maths Chapter 1 Relations and Functions describes all the fundamental concepts covered in this most important algebraic topic. The mathematical term relation is drawn from the English word relation that implies two objects or quantities have a recognizable connection. Students have already studied the notion of relations, functions, domain, co-domain, and range in class 11. Chapter 1 of class 12 maths further elaborates the types of relations, functions, composition of functions, invertible functions, and binary operations. By learning through NCERT Solutions Class 12 Maths Chapter 1, students will get well-versed with all these topics and their applications.

Some of the types of relations explained in this chapter are empty relation, universal relation, symmetric relation, and transitive relation. An empty relation is also known as a void relation and is defined as a set in which there exists no relationship between the elements. With the regular practice of Class 12 Maths NCERT Solutions Chapter 1, students will quickly gain a deep understanding of Relations and their types.
