critical f(x,y)=x^2y-x^2-1/3 y^3

critical points

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

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

Solution steps

x^{2} y - x^{2} - \frac{1}{3} y^{3}

Find where

\nabla f (x, y)

is equal to zero or undefined

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

f (x) = \frac{4 e ^{x}}{4 e ^{x} + 4}

f (x) = 2 + x + \frac{7}{x}

y = 2 + 12 x - x^{3}

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

f (x) = \frac{( 3 x ^{2} - 11 )}{( x ^{2} - 4 )}
