extreme x^3-x^2-x+3

Solution

extreme points

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

Solution

Maximum (- \frac{1}{3}, \frac{86}{27}), Minimum (1, 2)

Solution steps

f^{'} (x) = 3 x^{2} - 2 x - 1

Find intervals:

Increasing

: - \infty < x < - \frac{1}{3},

Decreasing

: - \frac{1}{3} < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - \frac{1}{3}

into

x^{3} - x^{2} - x + 3 : \frac{86}{27}

Maximum (- \frac{1}{3}, \frac{86}{27})

Plug

x = 1

into

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

Minimum (1, 2)

Maximum (- \frac{1}{3}, \frac{86}{27}), Minimum (1, 2)
