critical f(x,y)=2x^3+y^3-3x^2-3y

critical points

f (x, y) = 2 x^{3} + y^{3} - 3 x^{2} - 3 y

(0, 1), (0, - 1), (1, 1), (1, - 1)

Solution steps

2 x^{3} + y^{3} - 3 x^{2} - 3 y

Find where

\nabla f (x, y)

is equal to zero or undefined

(0, 1), (0, - 1), (1, 1), (1, - 1)

f (x) = x^{2} + 6 x y + 10 y^{2} - 4 y + 4

f (x, y) = - x^{2} - 4 y^{2} - a x + a x y

f (x) = (x^{\frac{3}{4}} - 2 x^{\frac{1}{4}})

f (x) = x^{4} - 4 x^{3} + 9

f (x) = 4 x^{\frac{1}{2}} - x^{\frac{5}{2}} [0.4]
