WebA twice differentiable function of several variables is strictly convex on a convex set if its Hessian matrix is positive definite on the interior of the convex set. Any local minimum of a convex function is also a global minimum. A strictly convex function will have at most one global minimum. Regardless of the format, the graph of a univariate quadratic function is a parabola (as shown at the right). Equivalently, this is the graph of the bivariate quadratic equation . • If a > 0, the parabola opens upwards. • If a < 0, the parabola opens downwards.
