extreme f(x)=(1-x^2)^2

extreme points

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

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

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < - 1,

Increasing

: - 1 < x < 0,

Decreasing

: 0 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - 1

into

(1 - x^{2})^{2} : 0

Minimum (- 1, 0)

Plug

x = 0

into

(1 - x^{2})^{2} : 1

Maximum (0, 1)

Plug

x = 1

into

(1 - x^{2})^{2} : 0

Minimum (1, 0)

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