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

extreme points

Maximum (- \frac{2 3}{5}, \frac{4 3}{5 ^{\frac{5}{6}}}), Minimum (\frac{2 3}{5}, - \frac{4 3}{5 ^{\frac{5}{6}}})

Solution steps

Find the critical points:

x = - 2, x = - \frac{2 3}{5}, x = \frac{2 3}{5}, x = 2

Domain of

Find intervals:

Increasing

: - \infty < x < - 2,

Increasing

: - 2 < x < - \frac{2 3}{5},

Decreasing

: - \frac{2 3}{5} < x < \frac{2 3}{5},

Increasing

: \frac{2 3}{5} < x < 2,

Increasing

: 2 < x < \infty

Plug the extreme point

x = - \frac{2 3}{5}

into

Maximum (- \frac{2 3}{5}, \frac{4 3}{5 ^{\frac{5}{6}}})

Plug the extreme point

x = \frac{2 3}{5}

into

Minimum (\frac{2 3}{5}, - \frac{4 3}{5 ^{\frac{5}{6}}})

Maximum (- \frac{2 3}{5}, \frac{4 3}{5 ^{\frac{5}{6}}}), Minimum (\frac{2 3}{5}, - \frac{4 3}{5 ^{\frac{5}{6}}})
