Solution

inflection points

\frac{x ^{3}}{3} - x^{2} - 15 x

Solution

(1, - \frac{47}{3})

Solution steps

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

Find intervals:

Concave Downward

: - \infty < x < 1,

Concave Upward

: 1 < x < \infty

Plug

x = 1

into

\frac{x ^{3}}{3} - x^{2} - 15 x : - \frac{47}{3}

(1, - \frac{47}{3})
