Let be a function that allows continuous second partial derivatives, we know that: Vƒ(x,y) = (16x³ - xy², 4y³ - x²y + 24y² + 36y) fxx = 48x² - y² fyy = 12y² - x² + 48y + 36 fxy = -2xy Consider the critic point (a,b) with negative X coordinates, that point generates a saddle point. What's the value for a and b?
