critical f(x)=-11*y^2+(x+16)^2+1

critical points

f (x) = - 11 \cdot y^{2} + (x + 16)^{2} + 1

(- 16, 0)

Solution steps

- 11 y^{2} + (x + 16)^{2} + 1

Find where

\nabla f (x, y)

is equal to zero or undefined

(- 16, 0)

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

f (x) = \frac{( 2 x - 1 )}{x + 1}

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

- \frac{2 x ( - x ^{2} + 27 )}{( x ^{2} + 9 ) ^{3}}

f (x) = x^{\frac{3}{2}} (3 x + 10)
