In a nutshell, functions are relations and relations are formed by two sets: an input set known as domain (X) and an output set known as range (Y).

What are the domain and the range of a function?</h3>
Herein we must give definition for a domain and a range of a function. According to function theory, functions are a kind of relations between two sets: an input set known as domain (X) and an output set known as range (Y).
Functions are relations in which an element of the former is related to an element of the latter such that this condition is fulfilled: x → y₁ and x → y₂, where y₁ = y₂.
