extreme f(x)=2x^3+3x^2+4

extreme points

f (x) = 2 x^{3} + 3 x^{2} + 4

Maximum (- 1, 5), Minimum (0, 4)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < 0,

Increasing

: 0 < x < \infty

Plug

x = - 1

into

2 x^{3} + 3 x^{2} + 4 : 5

Maximum (- 1, 5)

Plug

x = 0

into

2 x^{3} + 3 x^{2} + 4 : 4

Minimum (0, 4)

Maximum (- 1, 5), Minimum (0, 4)
