inflection (2x)/(x^2-1)

Solution

inflection points

\frac{2 x}{x ^{2} - 1}

Solution

(0, 0)

Solution steps

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

Find intervals:

Concave Downward

: - \infty < x < - 1,

Concave Upward

: - 1 < x < 0,

Concave Downward

: 0 < x < 1,

Concave Upward

: 1 < x < \infty

Plug

x = 0

into

\frac{2 x}{x ^{2} - 1} : 0

(0, 0)
