extreme f(x)=-x^2-6x-8

Solution

extreme points

f (x) = - x^{2} - 6 x - 8

Solution

Maximum (- 3, 1)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 3,

Decreasing

: - 3 < x < \infty

Plug

x = - 3

into

- x^{2} - 6 x - 8 : 1

Maximum (- 3, 1)

Popular Examples

extreme f(x)=(2x)/(1+x^2)extreme points

f (x) = \frac{2 x}{1 + x ^{2}}

extreme f(x,y)=x^2+2y^2-x^2y extreme points

f (x, y) = x^{2} + 2 y^{2} - x^{2} y

extreme x+(32)/(x^2)extreme points

x + \frac{32}{x ^{2}}

extreme f(x,y)=sqrt(1-x^2)-sqrt(4-y^2)extreme points

f (x, y) = 1 - x^{2} - 4 - y^{2}

extreme f(x)=x-2cos(x),0<= x<= 2pi extreme points

f (x) = x - 2 cos (x), 0 \leq x \leq 2 π
