inflection f(x)=x^2ln(x/6)

inflection points

f (x) = x^{2} ln (\frac{x}{6})

(\frac{6}{e ^{\frac{3}{2}}}, - \frac{54}{e ^{3}})

Solution steps

f^{''} (x) = 2 ln (\frac{x}{6}) + 3

Find intervals:

Concave Downward

: 0 < x < \frac{6}{e ^{\frac{3}{2}}},

Concave Upward

: \frac{6}{e ^{\frac{3}{2}}} < x < \infty

Plug

x = \frac{6}{e ^{\frac{3}{2}}}

into

x^{2} ln (\frac{x}{6}) : - \frac{54}{e ^{3}}

(\frac{6}{e ^{\frac{3}{2}}}, - \frac{54}{e ^{3}})

f (x) = \frac{8 e ^{x}}{e ^{x} - 6}

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

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

(- \frac{2}{6}) m = \frac{2}{3}

y = e^{x - 4}
