inflection x^{23/11}-x^{12/11}

inflection points

x^{\frac{23}{11}} - x^{\frac{12}{11}}

(\frac{1}{23}, (\frac{1}{23})^{\frac{23}{11}} - (\frac{1}{23})^{\frac{12}{11}})

Solution steps

f^{''} (x) = \frac{276 x - 12}{121 x ^{\frac{10}{11}}}

Find intervals:

Concave Downward

: - \infty < x < 0,

Concave Downward

: 0 < x < \frac{1}{23},

Concave Upward

: \frac{1}{23} < x < \infty

Plug

x = \frac{1}{23}

into

x^{\frac{23}{11}} - x^{\frac{12}{11}} : (\frac{1}{23})^{\frac{23}{11}} - (\frac{1}{23})^{\frac{12}{11}}

(\frac{1}{23}, (\frac{1}{23})^{\frac{23}{11}} - (\frac{1}{23})^{\frac{12}{11}})

\frac{1}{x ^{2} + 7}

\frac{x + 1}{x - 1}

f (x) = \frac{x}{144}

y = 5 tan (5 x - π)

(- 4, 5), (- 1, 8)
