extreme f(x)=(x^2-4)^{2/3}

extreme points

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

Minimum (- 2, 0), Maximum (0, (- 4)^{\frac{2}{3}}), Minimum (2, 0)

Solution steps

f^{'} (x) = \frac{4 x}{3 ( x ^{2} - 4 ) ^{\frac{1}{3}}}

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < 0,

Decreasing

: 0 < x < 2,

Increasing

: 2 < x < \infty

Plug

x = - 2

into

(x^{2} - 4)^{\frac{2}{3}} : 0

Minimum (- 2, 0)

Plug

x = 0

into

(x^{2} - 4)^{\frac{2}{3}} : (- 4)^{\frac{2}{3}}

Maximum (0, (- 4)^{\frac{2}{3}})

Plug

x = 2

into

(x^{2} - 4)^{\frac{2}{3}} : 0

Minimum (2, 0)

Minimum (- 2, 0), Maximum (0, (- 4)^{\frac{2}{3}}), Minimum (2, 0)

y = - 2 x

f (x) = \frac{9}{x + 4}

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

- \frac{1}{2} (x + 4)^{2} + 6

f (x) = - \frac{1}{2} \cdot 2^{x + 5} + 8
