inflection f(x)=3x^4+12x^3

Solution

inflection points

f (x) = 3 x^{4} + 12 x^{3}

Solution

(- 2, - 48), (0, 0)

Solution steps

f^{''} (x) = 36 x^{2} + 72 x

Find intervals:

Concave Upward

: - \infty < x < - 2,

Concave Downward

: - 2 < x < 0,

Concave Upward

: 0 < x < \infty

Plug

x = - 2

into

3 x^{4} + 12 x^{3} : - 48

(- 2, - 48)

Plug

x = 0

into

3 x^{4} + 12 x^{3} : 0

(0, 0)

(- 2, - 48), (0, 0)
