extreme 0.0025x^4+0.5x^3-8x^2+1000

extreme

Minimum (- 160, - 613400), Maximum (0, 1000), Minimum (10, 725)

Solution steps

f^{'} (x) = 0.01 x^{3} + 1.5 x^{2} - 16 x

Find intervals:

Decreasing

: - \infty < x < - 160,

Increasing

: - 160 < x < 0,

Decreasing

: 0 < x < 10,

Increasing

: 10 < x < \infty

Plug

x = - 160

into

0.0025 x^{4} + 0.5 x^{3} - 8 x^{2} + 1000 : - 613400

Minimum (- 160, - 613400)

Plug

x = 0

into

0.0025 x^{4} + 0.5 x^{3} - 8 x^{2} + 1000 : 1000

Maximum (0, 1000)

Plug

x = 10

into

0.0025 x^{4} + 0.5 x^{3} - 8 x^{2} + 1000 : 725

Minimum (10, 725)

Minimum (- 160, - 613400), Maximum (0, 1000), Minimum (10, 725)
