critical f(x)=x^2+9/(x^2)

critical points

f (x) = x^{2} + \frac{9}{x ^{2}}

x = - 3, x = 3

Solution steps

x^{2} + \frac{9}{x ^{2}}

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^{2} + \frac{9}{x ^{2}} : x < 0 or x > 0

x^{2} + \frac{9}{x ^{2}}

is not defined at

x = 0

, therefore:

x = - 3, x = 3

What is the critical f(x)=x^2+9/(x^2) ?
The critical f(x)=x^2+9/(x^2) is x=-sqrt(3),x=sqrt(3)
