extreme y=-4x^3-6x^2+360x-12

extreme

Minimum (- 6, - 1524), Maximum (5, 1138)

Solution steps

f^{'} (x) = - 12 x^{2} - 12 x + 360

Find intervals:

Decreasing

: - \infty < x < - 6,

Increasing

: - 6 < x < 5,

Decreasing

: 5 < x < \infty

Plug

x = - 6

into

- 4 x^{3} - 6 x^{2} + 360 x - 12 : - 1524

Minimum (- 6, - 1524)

Plug

x = 5

into

- 4 x^{3} - 6 x^{2} + 360 x - 12 : 1138

Maximum (5, 1138)

Minimum (- 6, - 1524), Maximum (5, 1138)
