a.Find the critical points of the given function and then determine whether it is a local maximum, local minimum, or saddle point.
f(x, y) = 5x2 + 2xy + 2x + y2 + y + 6
b.
f(x, y) = 2y3 + 12x2 ? 24xy.
(If an answer does not exist, enter DNE.)
a. Find the critical point of the given function and then determine whether it is a local maximum, local minimum, or saddle point.
f(x, y) = x2 â y2 + 3xy
b. Find the critical point of the given function and then determine whether it is a local maximum, local minimum, or saddle point.
f(x, y) = x2 + y2 â xy
