Relations Definition

A function exists between two sets.  Both the sets should not be empty.  The two sets are called set A and set B. Set A contains elements that are called Domain. It is also called pre-image.Set B contains elements that are called Co-domain.  It is also called image. They are matched by arrow diagrams. 
If the elements of set A are matched against all the elements of set B, then the elements in set B are called range. Range can also be subset of co-domain. The relation between set A and set B is called the function.  It is denoted by the letter 'f'
Let f : A → B  has a function.
