extreme f(x)=-2x^3+42x^2-240x+5

extreme

Minimum (4, - 411), Maximum (10, - 195)

Solution steps

f^{'} (x) = - 6 x^{2} + 84 x - 240

Find intervals:

Decreasing

: - \infty < x < 4,

Increasing

: 4 < x < 10,

Decreasing

: 10 < x < \infty

Plug

x = 4

into

- 2 x^{3} + 42 x^{2} - 240 x + 5 : - 411

Minimum (4, - 411)

Plug

x = 10

into

- 2 x^{3} + 42 x^{2} - 240 x + 5 : - 195

Maximum (10, - 195)

Minimum (4, - 411), Maximum (10, - 195)
