Let R be a binary relationMathworldPlanetmath. Then the set of all y such that xRy for some x is called the range of R. That is, the range of R is the set of all second coordinates in the ordered pairsMathworldPlanetmath of R.

In of functions, this means that the range of a function is the full set of values it can take on (the outputs), given the full set of parameters (the inputs). Note that the range is a subset of the codomain.
