critical x+4/x

Solution

critical points

x + \frac{4}{x}

Solution

x = - 2, x = 2

Solution steps

x + \frac{4}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 2, x = 2, x = 0

Identify critical points not in

f (x)

domain

Domain of

x + \frac{4}{x} : x < 0 or x > 0

x + \frac{4}{x}

is not defined at

x = 0

, therefore:

x = - 2, x = 2

Popular Examples

asymptotes of f(x)=((x-1))/(x+1)asymptotes

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

inverse of f(x)=(4x-2)/(x-1)inverse

f (x) = \frac{4 x - 2}{x - 1}

asymptotes of f(x)=(2x^2+4x)/(x^2-2x-8)asymptotes

f (x) = \frac{2 x ^{2} + 4 x}{x ^{2} - 2 x - 8}

symmetry y=x^3+2x-1 symmetry

y = x^{3} + 2 x - 1

domain of f(x)=2x-8 domain

f (x) = 2 x - 8
