inflection 1/3 x^3+2x^2-1

Solution

inflection points

\frac{1}{3} x^{3} + 2 x^{2} - 1

Solution

(- 2, \frac{13}{3})

Solution steps

f^{''} (x) = 2 x + 4

Find intervals:

Concave Downward

: - \infty < x < - 2,

Concave Upward

: - 2 < x < \infty

Plug

x = - 2

into

\frac{1}{3} x^{3} + 2 x^{2} - 1 : \frac{13}{3}

(- 2, \frac{13}{3})
