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

critical points

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

(- \frac{1}{2}, \frac{3}{2})

Solution steps

ln (x + y) + x^{2} - y

Find where

\nabla f (x, y)

is equal to zero or undefined

(- \frac{1}{2}, \frac{3}{2})

f (x) = ∣ 3 - 2 x ∣

f (x, y) = 2 x^{2} + 3 y^{2} - 12 x - 2 y + 1

f (x) = 3^{I n x}

f (x) = x e^{\frac{1}{x}}

f (x) = 6 x^{2}

What is the critical f(x,y)=ln(x+y)+x^2-y ?
