## Chapter 1: Relations and Functions

The term ‘relation’ in mathematics is derived from the English language’s definition of relationship, which states that two objects or quantities are linked if there is an observable connection or relation between them. This Class 12 Chapter 1 might be very confusing, therefore students can even use the strategies to improve in their learning.

Relation–An Empty relation R in X, can be defined relation as: R = φ ⊂ X × X- An Equivalence relation R in X is defined as a relation that can represent all the three types of relations: Reflexive, Symmetric, and Transitive relations.

- Symmetric relation R in X:
(a, b) ∈ R ⇒ (b, a) ∈ R.- Reflexive relation R in X:
(a, a) ∈ R, ∀ a ∈ X.- Transitive relation R in X:
(a, b) ∈ R and (b, c) ∈ R, ⇒ (a, c) ∈ R.- While, the Universal relation R in X:
R = X × X.Function-Depending on the conclusion obtained functions f: X → Y can be of different types like,

One-one or injective function:If f(x_{1}) = f(x_{2}) ⇒ x_{1}= x_{2}∀ x_{1}, x_{2}∈ X.Onto or surjective function: If y ∈ Y, ∃ x ∈ X such that f(x) = y.One-one and onto or bijective function: if f follows both the one-one and onto properties.Invertible function:If ∃ g: Y → X such that gof = I_{X}and fog = I_{Y}.
