Suppose f(x, y) = x² + y² - 10x - 6y+4 (A) How many critical points does f have in R²? (B) If there is a local minimum, what is the value of the discriminant D at that point? If there is none, type N. (C) If there is a local maximum, what is the value of the discriminant D at that point? If there is none, type N. (D) If there is a saddle point, what is the value of the discriminant D at that point? If there is none, type N. (E) What is the maximum value of f on R2? If there is none, type N. (F) What is the minimum value of f on R2? If there is none, type N.
