extreme f(x)=-x^3+15x^2+13

extreme

Minimum (0, 13), Maximum (10, 513)

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} + 13 : 13

Minimum (0, 13)

Plug

x = 10

into

- x^{3} + 15 x^{2} + 13 : 513

Maximum (10, 513)

Minimum (0, 13), Maximum (10, 513)

What is the extreme f(x)=-x^3+15x^2+13 ?
The extreme f(x)=-x^3+15x^2+13 is Minimum(0,13),Maximum(10,513)
