critical f(x)=x^3+3/x

critical points

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

x = - 1, x = 1

Solution steps

x^{3} + \frac{3}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 1, x = 1, x = 0

Identify critical points not in

f (x)

domain

Domain of

x^{3} + \frac{3}{x} : x < 0 or x > 0

x^{3} + \frac{3}{x}

is not defined at

x = 0

, therefore:

x = - 1, x = 1
