critical (2x)/(3(x^2-1)^{2/3)}

critical points

\frac{2 x}{3 ( x ^{2} - 1 ) ^{\frac{2}{3}}}

None

Solution steps

\frac{2 x}{3 ( x ^{2} - 1 ) ^{\frac{2}{3}}}

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}{3 ( x ^{2} - 1 ) ^{\frac{2}{3}}} : x < - 1 or - 1 < x < 1 or x > 1

\frac{2 x}{3 ( x ^{2} - 1 ) ^{\frac{2}{3}}}

is not defined at

x = - 1, x = 1

, therefore:

None

f (x) = e^{x^{2} - 5 x - 1}

1 + 6 x^{2} - x^{3}

4 x^{2} + 4 y^{2} + x^{4} + y^{4} - 6 x^{2} y^{2}

y = x^{\frac{4}{7}} (x^{2} - 6)

f (x) = \frac{x ^{3}}{3} - 3 x^{2} + 8 x - 4
