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

extreme points

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

Minimum (0, - 4), Maximum (2, 0)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < 2,

Decreasing

: 2 < x < \infty

Plug

x = 0

into

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

Minimum (0, - 4)

Plug

x = 2

into

- x^{3} + 3 x^{2} - 4 : 0

Maximum (2, 0)

Minimum (0, - 4), Maximum (2, 0)
