Class 12 Maths Chapter 1 – Ralations and Functions NCERT Solutions – FREE PDF Download |Hand – Written Notes | 2026-2027
Class 12 Mathematics Chapter 1, Relations and Functions, is the starting point of higher mathematics and forms the foundation for many advanced topics in calculus and algebra. This chapter helps students understand how different sets of numbers are connected and how one quantity depends on another. On EduTehri, Class 12 Maths Chapter 1 NCERT Solutions are designed to make these concepts simple, clear, and exam-ready.
What is Included in Chapter 1: Relations and Functions?
This chapter mainly focuses on understanding relations and functions between two non-empty sets. A relation is a connection between elements of one set to another set, while a function is a special type of relation where every input has exactly one output. Students also learn how functions are represented and how different types of functions behave.
Chapter 1 introduces important terms like domain, codomain, and range, which help in identifying the values for which a function is defined. The chapter also explains the algebra of functions, where functions are added, subtracted, multiplied, and divided. Another key part of this chapter is the composition of functions, which shows how two or more functions can be combined to form a new function.
Important Topics Covered in Chapter 1
The following are the most important topics students must focus on in Class 12 Maths Chapter 1:
• Definition of relations and functions
• Representation of relations (set-builder form and ordered pairs)
• Domain, codomain, and range of a function
• Types of functions (one-one, onto, many-one)
• Algebra of real-valued functions
• Composition of functions and identity function
These topics are frequently tested in board exams and form the base for chapters like inverse trigonometric functions and calculus.
