inflection f(x)=6x^3+36x^2+54x

Solution

inflection points

f (x) = 6 x^{3} + 36 x^{2} + 54 x

Solution

(- 2, - 12)

Solution steps

f^{''} (x) = 36 x + 72

Find intervals:

Concave Downward

: - \infty < x < - 2,

Concave Upward

: - 2 < x < \infty

Plug

x = - 2

into

6 x^{3} + 36 x^{2} + 54 x : - 12

(- 2, - 12)
