extreme f(x)=-2x^2-16x-31

Solution

extreme points

f (x) = - 2 x^{2} - 16 x - 31

Solution

Maximum (- 4, 1)

Solution steps

f^{'} (x) = - 4 x - 16

Find intervals:

Increasing

: - \infty < x < - 4,

Decreasing

: - 4 < x < \infty

Plug

x = - 4

into

- 2 x^{2} - 16 x - 31 : 1

Maximum (- 4, 1)

Popular Examples

extreme y=x^2-2x+1 extreme points

y = x^{2} - 2 x + 1

extreme f(x)=(x^2-35)/(x-6)extreme points

f (x) = \frac{x ^{2} - 35}{x - 6}

extreme x^3-18x^2+81x extreme points

x^{3} - 18 x^{2} + 81 x

extreme f(x,y)=x^2+xy+y^2+8y extreme points

f (x, y) = x^{2} + x y + y^{2} + 8 y

extreme f(x,y)=x^2+xy+y^2+5y extreme points

f (x, y) = x^{2} + x y + y^{2} + 5 y
