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

critical points

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

(- 2, - 2)

Solution steps

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

Find where

\nabla f (x, y)

is equal to zero or undefined

(- 2, - 2)

f (x, y) = x^{2} + y^{2} - 2 x + 6 y + 10

- x^{3} + 3 x^{2} + 2

f (x) = 3 x^{2} - 2 x

\frac{x ^{2} - 5 x + 7}{x ^{2} - 6 x + 10}

f (x) = 8 x^{7} (1 - x)^{8}
