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

critical points

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

x = - 1, x = 1

Solution steps

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

Find where

f^{'} (x)

is equal to zero or undefined

x = - 1, x = 1

Identify critical points not in

f (x)

domain

Domain of

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

All critical points are in domain

x = - 1, x = 1

3 x + y = 0

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

f (x) = x^{4}

f (x) = - x

f (x) = - \frac{1}{5} x + 15

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