WebThe epigraph is the set of points laying on or above the function’s graph. A convex function has an epigraph that is a convex set. A convex function has an epigraph that is a convex set. If you’re unfamiliar with epigraphs and convex sets, this image shows you the basic idea behind those terms (Duchi, 2016): WebWhat is true is that every function that is finite and convex on an open interval is continuous on that interval (including Rn). But for instance, a function f defined as f(x) = − √x for x &gt; 0 and f(0) = 1 is convex on [0, 1), but not continuous. – Michael Grant Aug 15, 2014 at 19:33 8
