What are Relations?

A relation is a set of ordered pairs (x, y) where x is called the independent variable and y is called the dependent variable. The relation between x and y is defined by a rule that assigns a unique value of y for each value of x. Sets Relations and Functions class 12 notes contain this definition along with some examples.

What are Functions?

A function is a special type of relation in which each value of x corresponds to exactly one value of y. The relation between x and y is defined by a rule or formula, and the dependent variable y is said to be a function of x.

Notation:

The function is denoted by f(x), where x is the independent variable and f(x) is the dependent variable.

Types of Functions:

One-to-One (Injective) Function: A function is said to be one-to-one if no two different values of x correspond to the same value of y.

Onto (Surjective) Function: A function is said to be onto if for every value of y, there exists at least one value of x that corresponds to it.

One-to-One Correspondence (Bijective) Function: A function is said to be a one-to-one correspondence if it is both one-to-one and onto.
