critical f(x,y)=4x^2y+2xy^2-12xy-5

critical points

f (x, y) = 4 x^{2} y + 2 x y^{2} - 12 x y - 5

(1, 2), (0, 6)

Solution steps

4 x^{2} y + 2 x y^{2} - 12 x y - 5

Find where

\nabla f (x, y)

is equal to zero or undefined

(1, 2), (0, 6)

f (x) = 2 x^{3} + 9 x^{2} + 12 x + 1

f (x) = x^{- 2} ln (x)

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

f (x) = 2 cos (x) + sin^{2} (x)

f (x) = 3 x^{4} + 4 x^{3} - 12 x^{2} + 7
