critical f(x,y)=x^3-6xy+8y^3

critical points

f (x, y) = x^{3} - 6 x y + 8 y^{3}

(0, 0), (1, \frac{1}{2})

Solution steps

x^{3} - 6 x y + 8 y^{3}

Find where

\nabla f (x, y)

is equal to zero or undefined

(0, 0), (1, \frac{1}{2})

f (x) = 4 x^{2} - 3 x + 2

f (x) = x e^{x^{2}}

x^{3} - 3 x + 4

x^{3} - 3 x - 2

\frac{x + 1}{x - 3}
