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

critical points

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

Solution steps

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

Find where

\nabla f (x, y)

is equal to zero or undefined

x^{3} - 11

f (x, y) = e (x^{2} + 0.5 y^{2} - 4 x y - 3 x)

f (x, y) = x^{4} + y^{4} - 4 x - 32 y + 10
