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

extreme points

f (x) = - \frac{x ^{2}}{2} + \frac{x ^{3}}{3}

Maximum (0, 0), Minimum (1, - \frac{1}{6})

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = 0

into

- \frac{x ^{2}}{2} + \frac{x ^{3}}{3} : 0

Maximum (0, 0)

Plug

x = 1

into

- \frac{x ^{2}}{2} + \frac{x ^{3}}{3} : - \frac{1}{6}

Minimum (1, - \frac{1}{6})

Maximum (0, 0), Minimum (1, - \frac{1}{6})

\frac{x ^{2} - 4 x}{11}

f (x) = - x, x < 0

f (x) = \frac{2}{x - 9}

f (x) = - 3 x^{2} + 7

f (x) = \frac{1 + e ^{x}}{1 - e ^{x}}
