inflection 5x^4-30x^2

Solution

inflection points

5 x^{4} - 30 x^{2}

Solution

(- 1, - 25), (1, - 25)

Solution steps

f^{''} (x) = 60 x^{2} - 60

Find intervals:

Concave Upward

: - \infty < x < - 1,

Concave Downward

: - 1 < x < 1,

Concave Upward

: 1 < x < \infty

Plug

x = - 1

into

5 x^{4} - 30 x^{2} : - 25

(- 1, - 25)

Plug

x = 1

into

5 x^{4} - 30 x^{2} : - 25

(1, - 25)

(- 1, - 25), (1, - 25)
