extreme f(x)=-2x^2-8x+5

Solution

extreme points

f (x) = - 2 x^{2} - 8 x + 5

Solution

Maximum (- 2, 13)

Solution steps

f^{'} (x) = - 4 x - 8

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < \infty

Plug

x = - 2

into

- 2 x^{2} - 8 x + 5 : 13

Maximum (- 2, 13)

Popular Examples

extreme f(x)=t-t^{1/3}extreme points

f (x) = t - t^{\frac{1}{3}}

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

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

extreme f(x,y)=3x^3-2x^2y+5xy-y^3-1 extreme points

f (x, y) = 3 x^{3} - 2 x^{2} y + 5 x y - y^{3} - 1

extreme f(x)=(3-x)e^{x-3}extreme points

f (x) = (3 - x) e^{x - 3}

extreme f(x)=1+x^2e^{5-3x}extreme points

f (x) = 1 + x^{2} e^{5 - 3 x}
