inflection f(x)=(x^2)/(8x^2+2)

inflection points

f (x) = \frac{x ^{2}}{8 x ^{2} + 2}

(- \frac{1}{2 3}, \frac{1}{32}), (\frac{1}{2 3}, \frac{1}{32})

Solution steps

f^{''} (x) = \frac{1 - 12 x ^{2}}{( 4 x ^{2} + 1 ) ^{3}}

Find intervals:

Concave Downward

: - \infty < x < - \frac{1}{2 3},

Concave Upward

: - \frac{1}{2 3} < x < \frac{1}{2 3},

Concave Downward

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

Plug

x = - \frac{1}{2 3}

into

\frac{x ^{2}}{8 x ^{2} + 2} : \frac{1}{32}

(- \frac{1}{2 3}, \frac{1}{32})

Plug

x = \frac{1}{2 3}

into

\frac{x ^{2}}{8 x ^{2} + 2} : \frac{1}{32}

(\frac{1}{2 3}, \frac{1}{32})

(- \frac{1}{2 3}, \frac{1}{32}), (\frac{1}{2 3}, \frac{1}{32})
