extreme f(x)=x(x^2-12)

extreme

Maximum (- 2, 16), Minimum (2, - 16)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < 2,

Increasing

: 2 < x < \infty

Plug

x = - 2

into

x (x^{2} - 12) : 16

Maximum (- 2, 16)

Plug

x = 2

into

x (x^{2} - 12) : - 16

Minimum (2, - 16)

Maximum (- 2, 16), Minimum (2, - 16)

What is the extreme f(x)=x(x^2-12) ?
The extreme f(x)=x(x^2-12) is Maximum(-2,16),Minimum(2,-16)
