critical f(x,y)=2x^2-xy-3y^2-3x+7y

critical points

f (x, y) = 2 x^{2} - x y - 3 y^{2} - 3 x + 7 y

(1, 1)

Solution steps

2 x^{2} - x y - 3 y^{2} - 3 x + 7 y

Find where

\nabla f (x, y)

is equal to zero or undefined

(1, 1)

y = 3 x^{4} + 4 x^{3} + x

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

f (x) = x \cdot e^{x}

e^{x^{2} - 8 x - 1}

y = x^{4} - 8 x^{2} + 3
