extreme y=(x^3)/3-2x^2-5x

extreme points

y = \frac{x ^{3}}{3} - 2 x^{2} - 5 x

Maximum (- 1, \frac{8}{3}), Minimum (5, - \frac{100}{3})

Solution steps

f^{'} (x) = x^{2} - 4 x - 5

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < 5,

Increasing

: 5 < x < \infty

Plug

x = - 1

into

\frac{x ^{3}}{3} - 2 x^{2} - 5 x : \frac{8}{3}

Maximum (- 1, \frac{8}{3})

Plug

x = 5

into

\frac{x ^{3}}{3} - 2 x^{2} - 5 x : - \frac{100}{3}

Minimum (5, - \frac{100}{3})

Maximum (- 1, \frac{8}{3}), Minimum (5, - \frac{100}{3})

f (x) = x^{3} - 3 x^{2} + 12, - 2 \leq x \leq 4

f (x) = \frac{1}{2} ln (\frac{1 + x}{1 - x}) - 2 x

f (x) = 6 x + 12 y - x^{2} - 3 y^{2}

f (x) = - 0.002 x^{2} + 4.4 x - 10

f (x) = x^{\frac{2}{5}} (x - 8)
