CBSE Class 11 Maths Notes Chapter 2
We will learn how to create a relation between two groups of things by linking pairs of objects in this chapter. We will examine how a function can be categorized as a connection. In conclusion, we will examine many categories of functions in addition to a few standard functions.Relations
Cartesian Product of Sets
Relation
Domain and Range of a Relation
The inverse of a Relation
Functions
A relation ‘f’ from set A to set B is said to be a function if every element of set A has one and only one image in set B.
Domain, Co-domain, and Range of a function
The domain is believed to be the biggest set of x values for which the formula provides real y - values when
is defined using a formula and the domain is not indicated explicitly.
The domain of y = f ( x ) 𝑦=𝑓(𝑥) is the set of all real x for which 𝑓(𝑥) is defined (real).

Kinds of Functions
Note:
-
Injective functions are called one-to-one functions.
-
Surjective functions are also known as onto functions.
-
Bijective functions are also known as (one-to-one) and (onto) functions.

Kinds of Functions
One-to-one or injective functions: There is only one corresponding element in set B for each element in set A. If there are elements in set B that match none in set A, then those elements might exist.
Onto or Surjective Functions: Functions that are onto or surjective have elements in set A that match one or more times for each member in set B.
Bijective functions: One-to-one and Onto functions are referred to as bijective functions. When every member has one matching element in the other set and no element is left out, this is also known as the perfect pairing.
