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

Solution

inflection points

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

Solution

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

Solution steps

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

Find intervals:

Concave Upward

: - \infty < x < 2,

Concave Downward

: 2 < x < \infty

Plug

x = 2

into

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

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