Equivalently, a function is convex if its epigraph (the set of points on or above the graph of the function) is a convex set. A twice-differentiable … See more Let $${\displaystyle X}$$ be a convex subset of a real vector space and let $${\displaystyle f:X\to \mathbb {R} }$$ be a function. Then $${\displaystyle f}$$ is called convex if and only if any of … See more The term convex is often referred to as convex down or concave upward, and the term concave is often referred as concave down or convex upward. If the term "convex" is used without an "up" or "down" keyword, then it refers strictly to a cup shaped graph See more The concept of strong convexity extends and parametrizes the notion of strict convexity. A strongly convex function is also strictly convex, but not vice versa. A differentiable function $${\displaystyle f}$$ is called strongly convex with parameter See more • Concave function • Convex analysis • Convex conjugate • Convex curve See more Many properties of convex functions have the same simple formulation for functions of many variables as for functions of one variable.
