Domain of a function

set theory, the domain of definition (or simply the domain) of a function is the set of "input" or argument values for which the function is defined. That

Surjective function

the fact that the image of the domain of a surjective function completely covers the function's codomain. Any function induces a surjection by restricting

Partial function

called a total function and is equivalent to a function. Partial functions are often used when the exact domain, X, is not known (e.g. many functions in computability
