extreme f(x)=9+3x^2-2x^3

extreme

Minimum (0, 9), Maximum (1, 10)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = 0

into

9 + 3 x^{2} - 2 x^{3} : 9

Minimum (0, 9)

Plug

x = 1

into

9 + 3 x^{2} - 2 x^{3} : 10

Maximum (1, 10)

Minimum (0, 9), Maximum (1, 10)
