NCERT Solutions for Class 12 Maths Chapter 1

The first section of NCERT Class 12 Maths goes into the topics of Relations and Functions. Students will be given a review of what they learned in the prior class. The evaluation will prepare the way for a deeper knowledge of the essential topics in Chapter 1 of 12th class Mathematics. A learner will also understand the quantitative relationship that exists between two groups of items. With the offered set of instructions, all of the main concepts relevant to relations as well as functions may be readily understood. It is necessary to review the concepts presented in the previous class in order to fully comprehend the NCERT answers for 12th class Maths Chapter 1. By completing the tasks, students will get a better knowledge of the subjects discussed in Chapter 1. They will be able to build a good understanding of the characteristics of Relations and Functions by attentively working through the exercises and solving the sums in Chapter 1. As one solves the sums one after another, the difficulty level will rise from easy to challenging. Students will find it easy to answer each question with greatest clarity if they have a general understanding of Chapter 1.

Recall

Learners will review several subjects from the previous lecture relevant to Relations as well as Functions in NCERT 12th class Mathematics Chapter 1 Solutions. They will have a better knowledge of veritable as well as invertible functions if these subjects are revisited. They will have a better comprehension of this section if they have a thorough understanding of real numbers and how to use addition, multiplication, division, as well as subtraction. In addition, this chapter includes information on how the use of relations emphasises the complementary integer. It will also pave the way for a better knowledge of the domain and co-domain in terms of function concepts.

Types of Functions

Identical function, continuous function, polynomial function, rationality function, exponent function, signum function, and other sorts of functions are discussed in the preceding section. Understanding the link between the injective as well as surjective functions will be easier as a result of this. It will also be revealed how the constituents of three separate numbers are linked to a host element. It also provides you a better knowledge of both continuous and discrete sets.

Example Question to solve:

  1. The domain of the function f(x)=1/(sqrt(|x|-x)) is: (A) (-oo,oo) (B) (0,oo (C) (-oo,””0) (D) (-oo,oo)”-“{0}

Composition of Functions and Invertible Function

This chapter will look at how the functions are composed and how the inverse property of bijective works. After you are able to grasp this concept, you will be given examples that explore the link between the set and the codes. This portion of the chapter focuses on the merging of two independent functions and how a code might be added to it in the end.

Binary Operations

Beginning in junior high, you should be familiar with the basic ideas of the BODMAS rule. It will demonstrate how operational functions aid in the induction of two numbers and, as a result, how binary operations are employed to merge two integers into one. You’ll be able to handle every part of the business. You’ll also learn about the binary operation, that involves a series of numbers being finally replaced by an arbitrary set of numbers. Furthermore, acquiring a deeper knowledge of the topics taught in this chapter will be aided by the formulation of the pair corresponding to the components.
