extreme f(x)=2x^3+30x^2+144x-1

extreme

Maximum (- 6, - 217), Minimum (- 4, - 225)

Solution steps

f^{'} (x) = 6 x^{2} + 60 x + 144

Find intervals:

Increasing

: - \infty < x < - 6,

Decreasing

: - 6 < x < - 4,

Increasing

: - 4 < x < \infty

Plug

x = - 6

into

2 x^{3} + 30 x^{2} + 144 x - 1 : - 217

Maximum (- 6, - 217)

Plug

x = - 4

into

2 x^{3} + 30 x^{2} + 144 x - 1 : - 225

Minimum (- 4, - 225)

Maximum (- 6, - 217), Minimum (- 4, - 225)
