Term "function" is given.

Definition 0.1 is as follows:

A function from a set A to set B is an assignment f that associates to each element x of the domain of set A exactly one element f(x) of the codomain or target set B

Each combination of real numbers (x, y) in the domain of a function f of two different variables is assigned a real number f(x, y).

Each combination of real numbers (x, y, z) in the domain of a function f of three different variables is assigned a real number f(x, y, z).
