WebA function of a single variable is concave if every line segment joining two points on its graph does not lie above the graph at any point. Symmetrically, a function of a single variable is convex if every line segment joining two points on its graph does not lie below the graph at any point. These concepts are illustrated in the following figures. WebShort answer: no. Since the function f is not defined by some formula, only by the graph sal draw, you cant say wether or not these are parabolas. That being said, let's assume f (x) …
