CODOMAIN
Etymology
Noun
codomain (plural codomains)
(mathematics, analysis) The target set into which a function is formally defined to map elements of its domain; the set denoted Y in the notation f : X → Y.
Usage notes
The codomain always contains the image of the function (the actual set of points to which points of the domain are mapped), and can be larger if the function is not surjective.
The term range is often synonymous with codomain, but can also be used as a synonym for image.
