extreme \sqrt[3]{(x^2-4)^2}

extreme points

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < 0,

Decreasing

: 0 < x < 2,

Increasing

: 2 < x < \infty

Plug

x = - 2

into

Minimum (- 2, 0)

Plug

x = 0

into

Plug

x = 2

into

Minimum (2, 0)
