extreme f(x)=x*ln(x)

Solution

extreme points

f (x) = x \cdot ln (x)

Solution

Minimum (\frac{1}{e}, - \frac{1}{e})

Solution steps

f^{'} (x) = ln (x) + 1

Find intervals:

Decreasing

: 0 < x < \frac{1}{e},

Increasing

: \frac{1}{e} < x < \infty

Plug

x = \frac{1}{e}

into

x \cdot ln (x) : - \frac{1}{e}

Minimum (\frac{1}{e}, - \frac{1}{e})
