extreme f(x)=x^3+6x^2+1

extreme points

f (x) = x^{3} + 6 x^{2} + 1

Maximum (- 4, 33), Minimum (0, 1)

Solution steps

f^{'} (x) = 3 x^{2} + 12 x

Find intervals:

Increasing

: - \infty < x < - 4,

Decreasing

: - 4 < x < 0,

Increasing

: 0 < x < \infty

Plug

x = - 4

into

x^{3} + 6 x^{2} + 1 : 33

Maximum (- 4, 33)

Plug

x = 0

into

x^{3} + 6 x^{2} + 1 : 1

Minimum (0, 1)

Maximum (- 4, 33), Minimum (0, 1)
