Solution

extreme points

x^{5} - 5 x^{4}

Solution

Maximum (0, 0), Minimum (4, - 256)

Solution steps

f^{'} (x) = 5 x^{4} - 20 x^{3}

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < 4,

Increasing

: 4 < x < \infty

Plug

x = 0

into

x^{5} - 5 x^{4} : 0

Maximum (0, 0)

Plug

x = 4

into

x^{5} - 5 x^{4} : - 256

Minimum (4, - 256)

Maximum (0, 0), Minimum (4, - 256)
