extreme f(x)=2x^3-9x^2-60x

extreme

Maximum (- 2, 68), Minimum (5, - 275)

Solution steps

f^{'} (x) = 6 x^{2} - 18 x - 60

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < 5,

Increasing

: 5 < x < \infty

Plug

x = - 2

into

2 x^{3} - 9 x^{2} - 60 x : 68

Maximum (- 2, 68)

Plug

x = 5

into

2 x^{3} - 9 x^{2} - 60 x : - 275

Minimum (5, - 275)

Maximum (- 2, 68), Minimum (5, - 275)
