{{dablink|For the more general concept of the graph of a relation, see ''[[relation]]''. For another use of the term "graph" in mathematics, see ''[[graph theory]]''.}}
In mathematics, the '''graph''' of a [[function (mathematics)|function]] ''f'' is the collection of all [[ordered pair]]s (''x'',''f''(''x'')). In particular, ''graph'' means the graphical representation of this collection, in the form of a [[curve]] or [[surface]], together with axes, etc. Graphing on a [[Cartesian coordinate system|Cartesian plane]] is sometimes referred to as '''curve sketching'''.
