inflection f(x)=x^3+3x^2+x+1

Solution

inflection points

f (x) = x^{3} + 3 x^{2} + x + 1

Solution

(- 1, 2)

Solution steps

f^{''} (x) = 6 x + 6

Find intervals:

Concave Downward

: - \infty < x < - 1,

Concave Upward

: - 1 < x < \infty

Plug

x = - 1

into

x^{3} + 3 x^{2} + x + 1 : 2

(- 1, 2)
