Multivalued function


 

In mathematics, a multivalued function is a total relation; i.e. every input is associated with one or more outputs. Strictly speaking, a "well-defined" function associates one, and only one, output to any particular input. The term "multivalued function" is, technically, a misnomer: true functions are single-valued. However, a multivalued function from A to B can be represented as a function from A to the power set of B.
