Functions Class 11 Mathematics Solutions | Exercise - 2.2
Chapter - 2
Functions
If you're studying mathematics in grade 11, you've probably come across the chapter on functions. In many textbooks, this chapter is listed as Chapter 2. Sometimes, when you're solving the problems in this chapter, you might face difficulties or get stuck. To assist you, I have the solutions for the class 11 function chapter.
In the function chapter, we will learn various methods to determine the domain and range of functions, as well as how to find the inverse of functions. This chapter consists of three exercises, each covering different subtopics related to functions. Before diving into the solutions section, let's gain a basic understanding of what functions are and how they work.
Introduction
A function is a way to describe how one set of things relates to another set of things. It establishes a connection or relationship between the elements of the first set and the elements of the second set. In this relationship, each element from the first set corresponds to exactly one element in the second set, and no element is left unmatched.
We can represent this relationship using mathematical notations. For example, f(x) indicates that the function is named "f" and it takes an input value "x" from the first set, producing a corresponding output value. Alternatively, we can use the equation form y = f(x), where the function f(x) determines the value of "y" based on the input value "x". These notations help us express and work with functions in a concise and meaningful way.
Inverse function
An inverse function, also known as an anti-function, is a function that can undo or reverse the action of another function. In simpler terms, if we have a function "f" that takes an input "x" and produces an output "y," then the inverse of "f" will take "y" as input and produce "x" as output.
To represent the inverse function, if the original function is denoted by 'f' or 'F', the inverse function is denoted by 'f⁻¹' or 'F⁻¹'. It's important not to confuse the '-1' notation used for the inverse function with exponents or reciprocals. In this context, the '-1' signifies the inverse relationship between the original function and its inverse.

How to secure good marks in Mathematics ?
As, you may know I'm also a student. Being a student is not so easy. You have to study different subjects simultaneously. From my point of view most of the student are weak in mathematics. You can take me as an example, I am also weak in mathematics. I also face problems while solving mathematics questions.
If you want to secure good marks in mathematics then you should practise them everyday. You should once revise all the exercise which are already taught in class. When you are solving maths problems, start from easy questions that you know already. If you do so then you won't get bored.
Maths is not only about practising, especially in grade 11 you to have the basic concept of the problem. When you get the main concept of the problem then you can easily any problems in which similar concept are applied.
When your teacher tries to make the concept clear by giving examples then all students tries to remember the same example but you should never do that. You can create your own formula which you won't forget later.
If you give proper time for your practise with proper technique then you can definitely score a good marks in your examination.
