critical f(x)=-3x^4-24x^2+4y^3-12y-20

critical points

f (x) = - 3 x^{4} - 24 x^{2} + 4 y^{3} - 12 y - 20

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

Solution steps

- 3 x^{4} - 24 x^{2} + 4 y^{3} - 12 y - 20

Find where

\nabla f (x, y)

is equal to zero or undefined

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

f (y) = 5 (9650 - y^{2}) - 19 y

x^{2} - 7 x + 2

x^{2} + y

2 x^{3} - x^{3} + \frac{x ^{4}}{4}
