extreme f(x)= 1/6 x^3-8x+19/3

extreme

Maximum (- 4, \frac{83}{3}), Minimum (4, - 15)

Solution steps

f^{'} (x) = \frac{x ^{2}}{2} - 8

Find intervals:

Increasing

: - \infty < x < - 4,

Decreasing

: - 4 < x < 4,

Increasing

: 4 < x < \infty

Plug

x = - 4

into

\frac{1}{6} x^{3} - 8 x + \frac{19}{3} : \frac{83}{3}

Maximum (- 4, \frac{83}{3})

Plug

x = 4

into

\frac{1}{6} x^{3} - 8 x + \frac{19}{3} : - 15

Minimum (4, - 15)

Maximum (- 4, \frac{83}{3}), Minimum (4, - 15)
