extreme f(x)=-x^2-2x+8

Solution

extreme points

f (x) = - x^{2} - 2 x + 8

Solution

Maximum (- 1, 9)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < \infty

Plug

x = - 1

into

- x^{2} - 2 x + 8 : 9

Maximum (- 1, 9)

Popular Examples
