WebMay 14, 2024 · However it is not strictly convex because for x = − 2 and y = 2 the inequality does not hold strictly. However, g ( x) = x 2 is strictly convex, for example. Every strictly convex function is also convex. The opposite is not necessarily true as the above example of f ( x) has shown. A strictly convex function will always take a unique minimum. In mathematics, a real-valued function is called convex if the line segment between any two distinct points on the graph of the function lies above the graph between the two points.
