extreme f(x)=-x^2-4x-3

Solution

extreme points

f (x) = - x^{2} - 4 x - 3

Solution

Maximum (- 2, 1)

Solution steps

f^{'} (x) = - 2 x - 4

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < \infty

Plug

x = - 2

into

- x^{2} - 4 x - 3 : 1

Maximum (- 2, 1)

Popular Examples

extreme f(x)=4x^3-2x^2 extreme points

f (x) = 4 x^{3} - 2 x^{2}

extreme f(x)=(1-cos(x))^2 extreme points

f (x) = (1 - cos (x))^{2}

extreme f(x,y)=sqrt(400-49x^2-81y^2)extreme points

f (x, y) = 400 - 49 x^{2} - 81 y^{2}

extreme f(x)=x^3-4.5x^2-12x-2 extreme points

f (x) = x^{3} - 4.5 x^{2} - 12 x - 2

extreme f(t)=3t+1/t extreme points

f (t) = 3 t + \frac{1}{t}
