**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.
