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

extreme points

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

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

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < 2,

Increasing

: 2 < x < \infty

Plug

x = - 1

into

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

Maximum (- 1, 10)

Plug

x = 2

into

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

Minimum (2, - 17)

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