CBSE Class 12 Maths Chapter 1 – Relations and Functions
Relations and Functions serve as the gateway to the Class 12 Maths syllabus. A relation establishes a logical connection between elements of two sets, typically expressed as ordered pairs. Understanding the classification of relations—specifically reflexive, symmetric, and transitive properties—is essential for identifying how elements interact within a mathematical set.
A function is a specialized relation where each element in the input set corresponds to exactly one unique output in the target set. The collection of all possible inputs is defined as the domain, while the set of corresponding outputs forms the range. Functions are categorized into various types, including one-one (injective), onto (surjective), and into functions, based on their mapping characteristics.
This chapter also explores advanced topics like inverse functions, which involve reversing the mapping direction, and the composition of functions, where two functions are combined to create a new mapping. To master these topics, students are encouraged to focus on core definitions and properties rather than relying solely on rote formula memorization.
