critical f(x,y)=x^2-2x+y^2+2y+1

critical points

f (x, y) = x^{2} - 2 x + y^{2} + 2 y + 1

(1, - 1)

Solution steps

x^{2} - 2 x + y^{2} + 2 y + 1

Find where

\nabla f (x, y)

is equal to zero or undefined

(1, - 1)

f (x) = (\frac{x ^{4}}{4} - x^{3} - 2 x^{2} + 3)

f (x) = 14 10 π x + \frac{160}{x}

f (x, y) = x + y - 1

f (x) = I n (2 x + 1)

\frac{2 x}{x ^{2} + 9} - 1
