extreme 2x^3+3x^2-12x+5

extreme points

2 x^{3} + 3 x^{2} - 12 x + 5

Maximum (- 2, 25), Minimum (1, - 2)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - 2

into

2 x^{3} + 3 x^{2} - 12 x + 5 : 25

Maximum (- 2, 25)

Plug

x = 1

into

2 x^{3} + 3 x^{2} - 12 x + 5 : - 2

Minimum (1, - 2)

Maximum (- 2, 25), Minimum (1, - 2)
