extreme f(x)=2x^2(ln(x))

extreme points

f (x) = 2 x^{2} (ln (x))

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

Solution steps

f^{'} (x) = 2 (2 x ln (x) + x)

Find intervals:

Decreasing

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

Increasing

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

Plug

x = \frac{1}{e}

into

2 x^{2} ln (x) : - \frac{1}{e}

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