inflection f(x)=x^3+6x^2+9x

Solution

inflection points

f (x) = x^{3} + 6 x^{2} + 9 x

Solution

(- 2, - 2)

Solution steps

f^{''} (x) = 6 x + 12

Find intervals:

Concave Downward

: - \infty < x < - 2,

Concave Upward

: - 2 < x < \infty

Plug

x = - 2

into

x^{3} + 6 x^{2} + 9 x : - 2

(- 2, - 2)
