The epigraph of a function f on a subset C of $R^n$ is the set of points (x, mu) of $R^{n+1}$ with x in C and mu at least f(x).

Statement

In the setting of Convex Functions on $\mathbb{R}^n$ : Standing Notation, let $C\subseteq\mathbb{R}^{n}$ and let $f:C\to\mathbb{R}$ be a function.

Epigraph. The epigraph of $f$ is the subset of $\mathbb{R}^{n+1}$

\operatorname{epi}f=\bigl\{(x,\mu):\ x\in C,\ \mu\in\mathbb{R},\ \mu\ge f(x)\bigr\}.
