extreme x^3-48x+7

Solution

extreme points

x^{3} - 48 x + 7

Solution

Maximum (- 4, 135), Minimum (4, - 121)

Solution steps

f^{'} (x) = 3 x^{2} - 48

Find intervals:

Increasing

: - \infty < x < - 4,

Decreasing

: - 4 < x < 4,

Increasing

: 4 < x < \infty

Plug

x = - 4

into

x^{3} - 48 x + 7 : 135

Maximum (- 4, 135)

Plug

x = 4

into

x^{3} - 48 x + 7 : - 121

Minimum (4, - 121)

Maximum (- 4, 135), Minimum (4, - 121)
