inflection f(x)=x^4-4x^3+2

Solution

inflection points

f (x) = x^{4} - 4 x^{3} + 2

Solution

(0, 2), (2, - 14)

Solution steps

f^{''} (x) = 12 x^{2} - 24 x

Find intervals:

Concave Upward

: - \infty < x < 0,

Concave Downward

: 0 < x < 2,

Concave Upward

: 2 < x < \infty

Plug

x = 0

into

x^{4} - 4 x^{3} + 2 : 2

(0, 2)

Plug

x = 2

into

x^{4} - 4 x^{3} + 2 : - 14

(2, - 14)

(0, 2), (2, - 14)
