inflection 5x^2ln(x/4)

inflection

(\frac{4}{e ^{\frac{3}{2}}}, - \frac{120}{e ^{3}})

Solution steps

f^{''} (x) = 5 (2 ln (\frac{x}{4}) + 3)

Find intervals:

Concave Downward

: 0 < x < \frac{4}{e ^{\frac{3}{2}}},

Concave Upward

: \frac{4}{e ^{\frac{3}{2}}} < x < \infty

Plug

x = \frac{4}{e ^{\frac{3}{2}}}

into

5 x^{2} ln (\frac{x}{4}) : - \frac{120}{e ^{3}}

(\frac{4}{e ^{\frac{3}{2}}}, - \frac{120}{e ^{3}})
