critical 1/3 y^3+4xy-9y-x^2

critical points

\frac{1}{3} y^{3} + 4 x y - 9 y - x^{2}

(1, 2), (- 9, - 18)

Solution steps

\frac{1}{3} y^{3} + 4 x y - 9 y - x^{2}

Find where

\nabla f (y, x)

is equal to zero or undefined

(1, 2), (- 9, - 18)

f (x) = 3 x^{3} - 5 x

f (x, y) = 12 x - x^{3} - 4 y^{2}

f (x) = ln (1 + x)

f (x, y) = 1 + 4 x + 4 y^{3} - x^{4} - y^{4}

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