extreme x^4-6x^2

extreme points

x^{4} - 6 x^{2}

Minimum (- 3, - 9), Maximum (0, 0), Minimum (3, - 9)

Solution steps

f^{'} (x) = 4 x^{3} - 12 x

Find intervals:

Decreasing

: - \infty < x < - 3,

Increasing

: - 3 < x < 0,

Decreasing

: 0 < x < 3,

Increasing

: 3 < x < \infty

Plug

x = - 3

into

x^{4} - 6 x^{2} : - 9

Minimum (- 3, - 9)

Plug

x = 0

into

x^{4} - 6 x^{2} : 0

Maximum (0, 0)

Plug

x = 3

into

x^{4} - 6 x^{2} : - 9

Minimum (3, - 9)

Minimum (- 3, - 9), Maximum (0, 0), Minimum (3, - 9)

f (x) = x^{2} - 8 x + 12

f (x) = x^{3} - 3 x^{2} - 9 x + 7

f (x) = x^{3} - 3 x^{2} - 9 x + 4

\frac{x}{ln ( x )}

f (x) = x^{3} - 3 x y - y^{2}
