inflection x^2ln(x)

פתרון

inflection points

x^{2} ln (x)

פתרון

(\frac{1}{e ^{\frac{3}{2}}}, - \frac{3}{2 e ^{3}})

צעדי פתרון

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

Find intervals:

Concave Downward

: 0 < x < \frac{1}{e ^{\frac{3}{2}}},

Concave Upward

: \frac{1}{e ^{\frac{3}{2}}} < x < \infty

Plug

x = \frac{1}{e ^{\frac{3}{2}}}

into

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

(\frac{1}{e ^{\frac{3}{2}}}, - \frac{3}{2 e ^{3}})
