extreme

Minimum (- 2, - 29), Maximum (0, 3), Minimum (2, - 29)

Solution steps

f^{'} (x) = 8 x^{3} - 32 x

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < 0,

Decreasing

: 0 < x < 2,

Increasing

: 2 < x < \infty

Plug

x = - 2

into

2 x^{4} - 16 x^{2} + 3 : - 29

Minimum (- 2, - 29)

Plug

x = 0

into

2 x^{4} - 16 x^{2} + 3 : 3

Maximum (0, 3)

Plug

x = 2

into

2 x^{4} - 16 x^{2} + 3 : - 29

Minimum (2, - 29)

Minimum (- 2, - 29), Maximum (0, 3), Minimum (2, - 29)
