Consider the function
f(x,y) = 2x^2 - 7y^2
Find and classify all critical points of the function. If there are more blanks than critical points, leave the remaining entries blank.
f_x =
f_y =
f_xx =
f_xy =
f_yy =
The critical point with the smallest x-coordinate is
( , ) Classification:
(local minimum, local maximum, saddle point, cannot be determined)
The critical point with the next smallest x-coordinate is
( , ) Classification:
(local minimum, local maximum, saddle point, cannot be determined)
The critical point with the next smallest x-coordinate is
( , ) Classification:
