Convex Functions: Definition, Properties with Solved Examples
A function is strictly convex if it lies above its tangent line at every point except for where the tangent line intersects the function. Convex functions have no local minima; the global minimum is at the point where the tangent line intersects the (x)-axis. Convex functions have second derivatives that are non-negative.
