critical f(x)=(x^2-1)/(x^3)

critical points

f (x) = \frac{x ^{2} - 1}{x ^{3}}

x = - 3, x = 3

Solution steps

\frac{x ^{2} - 1}{x ^{3}}

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

\frac{x ^{2} - 1}{x ^{3}} : x < 0 or x > 0

\frac{x ^{2} - 1}{x ^{3}}

is not defined at

x = 0

, therefore:

x = - 3, x = 3

What is the critical f(x)=(x^2-1)/(x^3) ?
The critical f(x)=(x^2-1)/(x^3) is x=-sqrt(3),x=sqrt(3)
