extreme f(x)= 1/3 x^3-x^2-3x+3

extreme

Maximum (- 1, \frac{14}{3}), Minimum (3, - 6)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < 3,

Increasing

: 3 < x < \infty

Plug

x = - 1

into

\frac{1}{3} x^{3} - x^{2} - 3 x + 3 : \frac{14}{3}

Maximum (- 1, \frac{14}{3})

Plug

x = 3

into

\frac{1}{3} x^{3} - x^{2} - 3 x + 3 : - 6

Minimum (3, - 6)

Maximum (- 1, \frac{14}{3}), Minimum (3, - 6)
