critical x+9/x

Solution

critical points

x + \frac{9}{x}

Solution

x = - 3, x = 3

Solution steps

x + \frac{9}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 3, x = 3, x = 0

Identify critical points not in

f (x)

domain

Domain of

x + \frac{9}{x} : x < 0 or x > 0

x + \frac{9}{x}

is not defined at

x = 0

, therefore:

x = - 3, x = 3

Popular Examples

critical f(x)=x^6+2x^4 critical points

f (x) = x^{6} + 2 x^{4}

critical f(x,y)=2x^2+y^4-2x^2y^2+3 critical points

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

critical f(x)=2x+(18)/x critical points

f (x) = 2 x + \frac{18}{x}

critical 2x^3-3xy+3y^3 critical points

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

critical y=x^3+(-3)x^2+b critical points

y = x^{3} + (- 3) x^{2} + b
