extreme f(x)=-2x^3+33x^2-144x+1

extreme

Minimum (3, - 188), Maximum (8, - 63)

Solution steps

f^{'} (x) = - 6 x^{2} + 66 x - 144

Find intervals:

Decreasing

: - \infty < x < 3,

Increasing

: 3 < x < 8,

Decreasing

: 8 < x < \infty

Plug

x = 3

into

- 2 x^{3} + 33 x^{2} - 144 x + 1 : - 188

Minimum (3, - 188)

Plug

x = 8

into

- 2 x^{3} + 33 x^{2} - 144 x + 1 : - 63

Maximum (8, - 63)

Minimum (3, - 188), Maximum (8, - 63)
