Welcome to UNIZOR.COM http://www.unizor.com.
The concept of a function includes three major components:
a set called "domain",
a set called "codomain" and
a rule which for each element of a domain points to (puts into a correspondence) a one and only one element from a codomain.
Elements of a domain are called "arguments" of this function and corresponding elements
of a codomain pointed to by an above mentioned rule are called "values" or "images" of this function.
