extreme f(x)=-x^3+15x^2

extreme

Minimum (0, 0), Maximum (10, 500)

Solution steps

f^{'} (x) = - 3 x^{2} + 30 x

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < 10,

Decreasing

: 10 < x < \infty

Plug

x = 0

into

- x^{3} + 15 x^{2} : 0

Minimum (0, 0)

Plug

x = 10

into

- x^{3} + 15 x^{2} : 500

Maximum (10, 500)

Minimum (0, 0), Maximum (10, 500)

What is the extreme f(x)=-x^3+15x^2 ?
The extreme f(x)=-x^3+15x^2 is Minimum(0,0),Maximum(10,500)
