# NCERT Solutions Class 12 Maths Chapter 1 Exercise 1.2 Relations and Functions

NCERT Solutions for Class 12 Maths Chapter 1 Exercise 1.2 Relations and Functions consists of questions based on types of functions. The topic of function is of paramount importance in mathematics; thus it is important to study these functions and their types deeply. Students have already learned the notion of some special functions like identity function, constant function, polynomial function, rational function, modulus function, signum function, etc in Class 11. This chapter will further explain the relations between the injective and the surjective function to solidify these concepts. A function is injective if the images of distinct elements of X under f are distinct, that is, for every x1, x2 ∈ X, f(x1) = f(x2) which implies x1 = x2. A function is said to be surjective if every element of a function Y is the image of some element of X under f, that is, for every y ∈ Y, there exists an element x in X such that f(x) = y.
