FAQs on RS Aggarwal Class 12 Solutions Chapter-1 Relation
1. Describe three types of Relation Functions?
There are three main types of related functions, and they are:
Injective Function - If a given element does not map two different elements from the same given domain to the same element in the range it is said to be a one-to-one or injective form of relation function.
Surjective Function - This function will only be correct if every member of set A will have at least one matching B. Doesn’t matter, the matching members of set B can be more than one.
Bijective Function - Bijective function is said to be a function that has both Injective and Surjective properties in the same sets. One can say it to be a perfect pairing between the sets in which every single member of the set has a partner, and no one is left out from the other set. As a result, it has a one-to-one correspondence between the members of the sets.
2. What is a Function and what are different types of Functions?
A function can be defined as the relation which is formed between two sets. Every single element in set 1 is associated with the elements present in set 2. In simple terms, if “f” is a function between X and Y, every element in the set X is considered the image of set Y. Given below, we have mentioned all the functions that students will learn in RS Aggarwal Class 12 Chapter 1 Solution.
One to One function.
One to Many functions.
Onto functions.
One to one Correspondence.
3.What are Binary Operations, and where can we use them?
We have basic maths operations, which are addition, subtraction, division, and multiplication, which can be easily performed on two given operands. In addition to this, when we are trying to add three numbers to one another, we go step by step, adding the first two and their answer with the third one. Thus, all the basic mathematical operations you see in your textbook are known as binary operations. The word binary means two, now taking an example where a set A and elements present in it are x, y, and z. The result of the operations we do on x and y will also be a part of the same set which is A. thus, and binary operations are said to be the operations performed on a set A.

5. How much weightage do Chapter 1 Relations of Class 12 Mathematics syllabus CBSE carry in the final board exam?
Chapter 1 of Class 12 CBSE MAthematics is part of unit 1 Relations and Functions which contains a total of 2 chapters: Relation and Inverse Trigonometric Functions. Both these chapters have a combined weightage of 8 marks in the final board exam which is conducted for 80 marks therefore 1/10th of the entire question paper. Students can refer to the class 12 NCERT textbook to get an idea about the types of questions asked from these two chapters and can practice numerical from the RS Aggrawal Solutions for Class 12 Mathematics.
