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

extreme points

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

Minimum (- 1, 0), Maximum (0, 1), Minimum (1, 0)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < - 1,

Increasing

: - 1 < x < 0,

Decreasing

: 0 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - 1

into

(x^{2} - 1)^{\frac{2}{3}} : 0

Minimum (- 1, 0)

Plug

x = 0

into

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

Maximum (0, 1)

Plug

x = 1

into

(x^{2} - 1)^{\frac{2}{3}} : 0

Minimum (1, 0)

Minimum (- 1, 0), Maximum (0, 1), Minimum (1, 0)

4 x + 2 y = 7

7 x - y = - 3

f (x) = \frac{7}{x + 6}

tan (3 x - 5)

\frac{2}{x ^{2} - 1}
