Learn functions from basics to advanced level for all.

A mathematical relation of an element with another element and vice-versa is called a function.

Generally, any element can have a relation with another element. Similarly, a set of elements can also have a relation with another set of elements. A mathematical concept is introduced in mathematics to understand and represent the relation between them, and it is called a function.

For example, $x$ is an element and it represents a quantity. Similarly, $y$ is an element and it also represents another quantity.

Assume, the element $x$ becomes $y$ by a relation between them. It happens in some cases. The mechanism of transformation of an element as another element is called a function.

The relation of two elements can be studied by the mathematics.
