funktioon
Funktioon is a theoretical construct used in discussions of functional abstraction in mathematics and computer science. The term is not standardized in established sources but is sometimes employed in instructional or speculative contexts to denote an idealized function-like operation.
Definition and scope: A funktioon is an abstract mapping that assigns to each input from its domain
Properties: In pure contexts, funktioon is deterministic and referentially transparent; its evaluation depends only on its
Examples: A square funktioon maps x to x*x; an add3 funktioon maps x to x+3. The composition
