critical f(x,y)=x^2-8x+y^2+14y

critical points

f (x, y) = x^{2} - 8 x + y^{2} + 14 y

(4, - 7)

Solution steps

x^{2} - 8 x + y^{2} + 14 y

Find where

\nabla f (x, y)

is equal to zero or undefined

(4, - 7)

f (x) = 5 x^{\frac{4}{5}} - 4 x

f (x) = 2 x^{3} - 5 x^{2} - 3 x + 10

\frac{e ^{x}}{1 - e ^{x}}

y = x^{\frac{5}{3}} - 5 x^{\frac{2}{3}}

y = \frac{2}{3} x^{3} - 2 x^{2} - 6 x
