extreme f(x)=x^3-75x

Solution

extreme points

f (x) = x^{3} - 75 x

Solution

Maximum (- 5, 250), Minimum (5, - 250)

Solution steps

f^{'} (x) = 3 x^{2} - 75

Find intervals:

Increasing

: - \infty < x < - 5,

Decreasing

: - 5 < x < 5,

Increasing

: 5 < x < \infty

Plug

x = - 5

into

x^{3} - 75 x : 250

Maximum (- 5, 250)

Plug

x = 5

into

x^{3} - 75 x : - 250

Minimum (5, - 250)

Maximum (- 5, 250), Minimum (5, - 250)
