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

critical points

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

x = - 3, x = 0, x = 3

Solution steps

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

Find where

f^{'} (x)

is equal to zero or undefined

x = - 3, x = 0, x = 3, x = - 1, x = 1

Identify critical points not in

f (x)

domain

Domain of

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

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

is not defined at

x = - 1, x = 1

, therefore:

x = - 3, x = 0, x = 3

What is the critical f(x)=x+x/(x^2-1) ?
The critical f(x)=x+x/(x^2-1) is x=-sqrt(3),x=0,x=sqrt(3)
