extreme f(x)=x^2+2/x

Solution

extreme points

f (x) = x^{2} + \frac{2}{x}

Solution

Minimum (1, 3)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 0,

Decreasing

: 0 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = 1

into

x^{2} + \frac{2}{x} : 3

Minimum (1, 3)
