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

critical points

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

(0, 0), (- \frac{2}{m ^{2}}, - \frac{2}{m ^{3}})

Solution steps

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

Find where

\nabla f (x, y)

is equal to zero or undefined

(0, 0), (- \frac{2}{m ^{2}}, - \frac{2}{m ^{3}})

f (x) = 2 x^{4} - 16 x^{3} + 20 x^{2} - 7

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

f (x) = - cos (x) - sin (x)

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

f (x) = \frac{2}{3} x^{3} - \frac{1}{2} x^{2} - 10 x - 1
