Range (mathematics)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematics, the range of a function f (denoted by mbox{ran},f ) is the set of all "output" values produced by f. Sometimes it is called the image, or more precisely, the image of the domain of the function. If a function is a surjection then its range is equal to its codomain. In a representation of a function in an xy Cartesian coordinate system, the range is represented on the ordinate (on the y axis). Sometimes the range means the set of all possible values - the codomain. This is also the current usage for range in computer science. The ambiguity makes it preferable to specify whether it is the image or the codomain being discussed.
