Tutorial Exercise Find the critical points, relative extrema, and saddle points of the function. f(x, y) = 2 - (x- 2)2 - (y+ 1)2 Step 1 Find the first partial derivatives of f(x, y) = 2 - (x - 2)2 - (y + 1)2 by holding first y, then x, constant. fx (x, y) = X - fy ( x, y ) = (y + 1) Submit Skip (you cannot come back) Need Help?
