+A **convex function** is a function where the line segment connecting any two points on its graph lies above or on the graph itself. This intrinsic "bowl-like" shape makes them fundamental in [Optimization](/wiki/optimization), guaranteeing that any local minimum is also a [Global Minimum](/wiki/global_minimum).
