Let us look at a simple example:
Domain, Range and Codomain    

In this illustration:

    the set "A" is the Domain,
    the set "B" is the Codomain,
    and the set of elements that get pointed to in B (the actual values produced by the function) are the Range, also called the Image.

    Domain: {1, 2, 3, 4}
    Codomain: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
