extreme f(x)=x^3-3x^2-24x-2

extreme

Maximum (- 2, 26), Minimum (4, - 82)

Solution steps

f^{'} (x) = 3 x^{2} - 6 x - 24

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < 4,

Increasing

: 4 < x < \infty

Plug

x = - 2

into

x^{3} - 3 x^{2} - 24 x - 2 : 26

Maximum (- 2, 26)

Plug

x = 4

into

x^{3} - 3 x^{2} - 24 x - 2 : - 82

Minimum (4, - 82)

Maximum (- 2, 26), Minimum (4, - 82)
