extreme x^3-3x^2-9x+10

extreme

Maximum (- 1, 15), Minimum (3, - 17)

Solution steps

f^{'} (x) = 3 x^{2} - 6 x - 9

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < 3,

Increasing

: 3 < x < \infty

Plug

x = - 1

into

x^{3} - 3 x^{2} - 9 x + 10 : 15

Maximum (- 1, 15)

Plug

x = 3

into

x^{3} - 3 x^{2} - 9 x + 10 : - 17

Minimum (3, - 17)

Maximum (- 1, 15), Minimum (3, - 17)
