extreme f(x)=x^4-32x^2+10

extreme

Minimum (- 4, - 246), Maximum (0, 10), Minimum (4, - 246)

Solution steps

f^{'} (x) = 4 x^{3} - 64 x

Find intervals:

Decreasing

: - \infty < x < - 4,

Increasing

: - 4 < x < 0,

Decreasing

: 0 < x < 4,

Increasing

: 4 < x < \infty

Plug

x = - 4

into

x^{4} - 32 x^{2} + 10 : - 246

Minimum (- 4, - 246)

Plug

x = 0

into

x^{4} - 32 x^{2} + 10 : 10

Maximum (0, 10)

Plug

x = 4

into

x^{4} - 32 x^{2} + 10 : - 246

Minimum (4, - 246)

Minimum (- 4, - 246), Maximum (0, 10), Minimum (4, - 246)
