critical (-2(x^2-1))/(x^2-4)

critical points

\frac{- 2 ( x ^{2} - 1 )}{x ^{2} - 4}

x = 0

Solution steps

\frac{- 2 ( x ^{2} - 1 )}{x ^{2} - 4}

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{- 2 ( x ^{2} - 1 )}{x ^{2} - 4} : x < - 2 or - 2 < x < 2 or x > 2

\frac{- 2 ( x ^{2} - 1 )}{x ^{2} - 4}

is not defined at

x = - 2, x = 2

, therefore:

x = 0

f (x) = x^{\frac{3}{2}} - 3 x^{\frac{5}{2}}

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

f (x) = x^{4} - 6 x^{3}

f (x) = x^{2} y + 2 x y^{2} - 2 x^{2} + 6 x y

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