extreme f(x)=4x^3-12x^2-96x+7

extreme

Maximum (- 2, 119), Minimum (4, - 313)

Solution steps

f^{'} (x) = 12 x^{2} - 24 x - 96

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < 4,

Increasing

: 4 < x < \infty

Plug

x = - 2

into

4 x^{3} - 12 x^{2} - 96 x + 7 : 119

Maximum (- 2, 119)

Plug

x = 4

into

4 x^{3} - 12 x^{2} - 96 x + 7 : - 313

Minimum (4, - 313)

Maximum (- 2, 119), Minimum (4, - 313)
