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

extreme

Maximum (- 2, 1), Minimum (0, - 3)

Solution steps

f^{'} (x) = 3 x^{2} + 6 x

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < 0,

Increasing

: 0 < x < \infty

Plug

x = - 2

into

x^{3} + 3 x^{2} - 3 : 1

Maximum (- 2, 1)

Plug

x = 0

into

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

Minimum (0, - 3)

Maximum (- 2, 1), Minimum (0, - 3)
