extreme f(x)=25x^2-x^3

extreme points

f (x) = 25 x^{2} - x^{3}

Minimum (0, 0), Maximum (\frac{50}{3}, \frac{62500}{27})

Solution steps

f^{'} (x) = 50 x - 3 x^{2}

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < \frac{50}{3},

Decreasing

: \frac{50}{3} < x < \infty

Plug

x = 0

into

25 x^{2} - x^{3} : 0

Minimum (0, 0)

Plug

x = \frac{50}{3}

into

25 x^{2} - x^{3} : \frac{62500}{27}

Maximum (\frac{50}{3}, \frac{62500}{27})

Minimum (0, 0), Maximum (\frac{50}{3}, \frac{62500}{27})

f (x) = 4 x^{2} - 16 x + 20

g (x) = - 50 x^{2} + 400 x + 500

f (x) = 4 x + 5 y

x^{11} - 3 x^{9} + 2

x^{3} - 2 x^{2} - 4 x - 4
