extreme f(x)=-2x^2-20x+8

Solution

extreme points

f (x) = - 2 x^{2} - 20 x + 8

Solution

Maximum (- 5, 58)

Solution steps

f^{'} (x) = - 4 x - 20

Find intervals:

Increasing

: - \infty < x < - 5,

Decreasing

: - 5 < x < \infty

Plug

x = - 5

into

- 2 x^{2} - 20 x + 8 : 58

Maximum (- 5, 58)

Popular Examples

extreme f(x)=x^5-x^3+1 extreme points

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

extreme y= x/(x^2+16)extreme points

y = \frac{x}{x ^{2} + 16}

extreme-x^3(x-3)extreme points

- x^{3} (x - 3)

extreme f(x)= 4/3 x^3-13/2 x^2-3x+11 extreme points

f (x) = \frac{4}{3} x^{3} - \frac{13}{2} x^{2} - 3 x + 11

extreme f(x)=3x^3-14x+20x-8 extreme points

f (x) = 3 x^{3} - 14 x + 20 x - 8
