inflection f(x)= x/(x^2-9)

Solution

inflection points

f (x) = \frac{x}{x ^{2} - 9}

Solution

(0, 0)

Solution steps

f^{''} (x) = - \frac{2 x ( - x ^{2} - 27 )}{( x ^{2} - 9 ) ^{3}}

Find intervals:

Concave Downward

: - \infty < x < - 3,

Concave Upward

: - 3 < x < 0,

Concave Downward

: 0 < x < 3,

Concave Upward

: 3 < x < \infty

Plug

x = 0

into

\frac{x}{x ^{2} - 9} : 0

(0, 0)
