Find and identify the critical points of the function f (x, y) = x³ + 3xy + y³ (Order them from the smallest x-value to the largest; enter both x and y- coordinates for a critical point) • The critical point at ( The critical point at ( ) is a ) is a (enter min for local minimum, max for local maximum, or SP for saddle point) Find and identify the critical points of the function f (x, y) = x³ + 3xy + y³ (Order them from the smallest x-value to the largest; enter both x and y- coordinates for a critical point) • The critical point at ( The critical point at ( ) is a ) is a (enter min for local minimum, max for local maximum, or SP for saddle point)
