In [[mathematics]], the '''graph''' of a [[Function (mathematics)|function]] <math>f</math> is the set of [[ordered pair]]s <math>(x, y)</math>, where <math>f(x) = y.</math> In the common case where <math>x</math> and <math>f(x)</math> are [[real number]]s, these pairs are [[Cartesian coordinates]] of points in [[two-dimensional space]] and thus form a subset of this plane.
