inflection f(x)=19x^4+76x^3

inflection points

f (x) = 19 x^{4} + 76 x^{3}

(- 2, - 304), (0, 0)

Solution steps

f^{''} (x) = 228 x^{2} + 456 x

Find intervals:

Concave Upward

: - \infty < x < - 2,

Concave Downward

: - 2 < x < 0,

Concave Upward

: 0 < x < \infty

Plug

x = - 2

into

19 x^{4} + 76 x^{3} : - 304

(- 2, - 304)

Plug

x = 0

into

19 x^{4} + 76 x^{3} : 0

(0, 0)

(- 2, - 304), (0, 0)
