extreme y=5+12x^2-8x^3

extreme

Minimum (0, 5), Maximum (1, 9)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = 0

into

5 + 12 x^{2} - 8 x^{3} : 5

Minimum (0, 5)

Plug

x = 1

into

5 + 12 x^{2} - 8 x^{3} : 9

Maximum (1, 9)

Minimum (0, 5), Maximum (1, 9)

What is the extreme y=5+12x^2-8x^3 ?
