Question 1 1 pts Suppose that f ( x, y ) = - xy + y - by" + 2y". This function has a critical point at (1, 1). Compute the determinant of the Hessian of f at this critical point. Your answer should be an integer.Question 2 1 pts Supposef (x, y) = a ty - 3x - 7y. How many of the critical points of f are saddle points
