codomain

codomain
Noun
pl: codomains

This term is a technical specification used in mathematics to define the target set of a function. It represents the entire space where the outputs are allowed to land, creating a boundary for the function's potential results. This differs from the range, which consists only of the values that are actually produced by the function.

In a practical sense, the codomain is a prerequisite for defining a function's type. While the range is a subset of the codomain, the codomain itself remains constant regardless of the specific inputs provided, serving as the formal destination set in mapping notation.
