critical f(x)=(x^2)/(4-x^2)

critical points

f (x) = \frac{x ^{2}}{4 - x ^{2}}

x = 0

Solution steps

\frac{x ^{2}}{4 - x ^{2}}

Find where

f^{'} (x)

is equal to zero or undefined

x = 0, x = - 2, x = 2

Identify critical points not in

f (x)

domain

Domain of

\frac{x ^{2}}{4 - x ^{2}} : x < - 2 or - 2 < x < 2 or x > 2

\frac{x ^{2}}{4 - x ^{2}}

is not defined at

x = - 2, x = 2

, therefore:

x = 0

What is the critical f(x)=(x^2)/(4-x^2) ?
The critical f(x)=(x^2)/(4-x^2) is x=0
