extreme f(x)=x^4-50x^2+6

extreme points

f (x) = x^{4} - 50 x^{2} + 6

Minimum (- 5, - 619), Maximum (0, 6), Minimum (5, - 619)

Solution steps

f^{'} (x) = 4 x^{3} - 100 x

Find intervals:

Decreasing

: - \infty < x < - 5,

Increasing

: - 5 < x < 0,

Decreasing

: 0 < x < 5,

Increasing

: 5 < x < \infty

Plug

x = - 5

into

x^{4} - 50 x^{2} + 6 : - 619

Minimum (- 5, - 619)

Plug

x = 0

into

x^{4} - 50 x^{2} + 6 : 6

Maximum (0, 6)

Plug

x = 5

into

x^{4} - 50 x^{2} + 6 : - 619

Minimum (5, - 619)

Minimum (- 5, - 619), Maximum (0, 6), Minimum (5, - 619)
