extreme f(x)=x^3-3x-1

extreme

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

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - 1

into

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

Maximum (- 1, 1)

Plug

x = 1

into

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

Minimum (1, - 3)

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