extreme f(x)=-2x^2-12x-23

Solution

extreme points

f (x) = - 2 x^{2} - 12 x - 23

Solution

Maximum (- 3, - 5)

Solution steps

f^{'} (x) = - 4 x - 12

Find intervals:

Increasing

: - \infty < x < - 3,

Decreasing

: - 3 < x < \infty

Plug

x = - 3

into

- 2 x^{2} - 12 x - 23 : - 5

Maximum (- 3, - 5)

Popular Examples

extreme x^2-xy+y^2+3x-2y-5 extreme points

x^{2} - x y + y^{2} + 3 x - 2 y - 5

extreme h(x)=(χ^2+4x-32)/(x^2-8x+16)extreme points

h (x) = \frac{χ ^{2} + 4 x - 32}{x ^{2} - 8 x + 16}

extreme f(x)=2x^36x^2-18x+1 extreme points

f (x) = 2 x^{3} 6 x^{2} - 18 x + 1

extreme f(x)=2x^3-y^2-6x+9y extreme points

f (x) = 2 x^{3} - y^{2} - 6 x + 9 y

extreme f(x,y)=y*e^{x^2-2y^2}extreme points

f (x, y) = y \cdot e^{x^{2} - 2 y^{2}}
