extreme x+1/x

Solution

extreme points

x + \frac{1}{x}

Solution

Maximum (- 1, - 2), Minimum (1, 2)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < 0,

Decreasing

: 0 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - 1

into

x + \frac{1}{x} : - 2

Maximum (- 1, - 2)

Plug

x = 1

into

x + \frac{1}{x} : 2

Minimum (1, 2)

Maximum (- 1, - 2), Minimum (1, 2)
