inflection f(x)=x^2ln(x/4)

inflection points

f (x) = x^{2} ln (\frac{x}{4})

(\frac{4}{e ^{\frac{3}{2}}}, - \frac{24}{e ^{3}})

Solution steps

f^{''} (x) = 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

x^{2} ln (\frac{x}{4}) : - \frac{24}{e ^{3}}

(\frac{4}{e ^{\frac{3}{2}}}, - \frac{24}{e ^{3}})

f (x) = x^{3} - 3 x^{2} - 9 x + 2

y = 1 - \frac{x}{8}

\frac{7 + x}{3 - x}

\frac{2}{3} (x - 2)^{3} + 6
