extreme f(x)=-10x^2-40x-2

Solution

extreme points

f (x) = - 10 x^{2} - 40 x - 2

Solution

Maximum (- 2, 38)

Solution steps

f^{'} (x) = - 20 x - 40

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < \infty

Plug

x = - 2

into

- 10 x^{2} - 40 x - 2 : 38

Maximum (- 2, 38)

Popular Examples

extreme f(x)=4x^2+y^2-8 extreme points

f (x) = 4 x^{2} + y^{2} - 8

extreme 10x^2-(250)/x extreme points

10 x^{2} - \frac{250}{x}

extreme f(x)=x^7(x+5)^8,-10<= x<= 10 extreme points

f (x) = x^{7} (x + 5)^{8}, - 10 \leq x \leq 10

extreme g(x)=x^3-9x extreme points

g (x) = x^{3} - 9 x

extreme (x^2-1)^3,-1<= x<= 6 extreme points

(x^{2} - 1)^{3}, - 1 \leq x \leq 6
