extreme (4x-ln(3x))/x

Solution

extreme

Solution

Minimum (\frac{e}{3}, \frac{4 e - 3}{e})

Solution steps

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

Find intervals:

Decreasing

: 0 < x < \frac{e}{3},

Increasing

: \frac{e}{3} < x < \infty

Plug

x = \frac{e}{3}

into

\frac{4 x - ln ( 3 x )}{x} : \frac{4 e - 3}{e}

Minimum (\frac{e}{3}, \frac{4 e - 3}{e})
