extreme f(x)=3(x^2+4)(x^2+8)^2

extreme points

f (x) = 3 (x^{2} + 4) (x^{2} + 8)^{2}

Minimum (0, 768)

Solution steps

f^{'} (x) = 3 (6 x^{5} + 80 x^{3} + 256 x)

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Plug

x = 0

into

3 (x^{2} + 4) (x^{2} + 8)^{2} : 768

Minimum (0, 768)
