Let f (x, y ) be a function and fxx = x + y, D (x, y ) = fxx fyy - fxy fxy = x - 3y2 . Then what is true for the critical points P (2 ,1 ) and Q ( 1, - 4 )? O a. P and Q are both local maximum. O b. P is local maximum, Q is local minimum. O C. P and Q are both local minimum. O d. P and Q are both saddle points.
