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
