extreme f(x)=10+12x-3x^2-2x^3

extreme points

f (x) = 10 + 12 x - 3 x^{2} - 2 x^{3}

Minimum (- 2, - 10), Maximum (1, 17)

Solution steps

f^{'} (x) = - 6 x^{2} - 6 x + 12

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = - 2

into

10 + 12 x - 3 x^{2} - 2 x^{3} : - 10

Minimum (- 2, - 10)

Plug

x = 1

into

10 + 12 x - 3 x^{2} - 2 x^{3} : 17

Maximum (1, 17)

Minimum (- 2, - 10), Maximum (1, 17)
