extreme f(x)=3x^4-54x^2+2

extreme

Minimum (- 3, - 241), Maximum (0, 2), Minimum (3, - 241)

Solution steps

f^{'} (x) = 12 x^{3} - 108 x

Find intervals:

Decreasing

: - \infty < x < - 3,

Increasing

: - 3 < x < 0,

Decreasing

: 0 < x < 3,

Increasing

: 3 < x < \infty

Plug

x = - 3

into

3 x^{4} - 54 x^{2} + 2 : - 241

Minimum (- 3, - 241)

Plug

x = 0

into

3 x^{4} - 54 x^{2} + 2 : 2

Maximum (0, 2)

Plug

x = 3

into

3 x^{4} - 54 x^{2} + 2 : - 241

Minimum (3, - 241)

Minimum (- 3, - 241), Maximum (0, 2), Minimum (3, - 241)
