A Function Range is the Output Set to a Function.
- AKA: Codomain, Range of a Function.
- Context:
- It can be associated to a Function Output Instance.
- …

- In mathematics, and more specifically in naive set theory, the range of a function refers to either the codomain or the image of the function, depending upon usage. Modern usage almost always uses range to mean image.
The codomain of a function is some arbitrary set. In real analysis, it is the real numbers. In complex analysis, it is the complex numbers.
The image of a function is the set of all outputs of the function. The image is always a subset of the codomain.

- QUOTE: We won't use these terms formally, but we can call s1 the domain of the function and s2 the range.
