Assume 2 C R" is open and convex, f E C²(N) (i.e., 2nd order partial derivatives are continuous in 2). Identify whether the statement is True or False. If xo E N is a local extremum point of f, then Vf(xo) = 0. Select one: O True O False Assume 2 C R" is open and convex, ƒ € C²(N) (i.e., 2nd order partial derivatives are continuous in 2). Identify whether the statement is True or False. If V² f(xo) is indefinite for some xo E N, then xo is a saddle point of f. Select one: O True O False
