extreme f(x)=(x^3)/3-6x^2+32x

extreme

Maximum (4, \frac{160}{3}), Minimum (8, \frac{128}{3})

Solution steps

f^{'} (x) = x^{2} - 12 x + 32

Find intervals:

Increasing

: - \infty < x < 4,

Decreasing

: 4 < x < 8,

Increasing

: 8 < x < \infty

Plug

x = 4

into

\frac{x ^{3}}{3} - 6 x^{2} + 32 x : \frac{160}{3}

Maximum (4, \frac{160}{3})

Plug

x = 8

into

\frac{x ^{3}}{3} - 6 x^{2} + 32 x : \frac{128}{3}

Minimum (8, \frac{128}{3})

Maximum (4, \frac{160}{3}), Minimum (8, \frac{128}{3})
