extreme y=x+(25)/x

Solution

extreme points

y = x + \frac{25}{x}

Solution

Maximum (- 5, - 10), Minimum (5, 10)

Solution steps

f^{'} (x) = 1 - \frac{25}{x ^{2}}

Find intervals:

Increasing

: - \infty < x < - 5,

Decreasing

: - 5 < x < 0,

Decreasing

: 0 < x < 5,

Increasing

: 5 < x < \infty

Plug

x = - 5

into

x + \frac{25}{x} : - 10

Maximum (- 5, - 10)

Plug

x = 5

into

x + \frac{25}{x} : 10

Minimum (5, 10)

Maximum (- 5, - 10), Minimum (5, 10)

Popular Examples

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

f (x) = \frac{3 x ^{2}}{x - 2}, - 2 \leq x \leq 1

extreme f(x)=x(16-41+2x)(41/2-x)extreme points

f (x) = x (16 - 41 + 2 x) (\frac{41}{2} - x)

extreme g(x,y)=sqrt(4-x^{(2))-y^{(2)}}extreme points

g (x, y) = 4 - x^{(2)} - y^{(2)}

extreme-2x^2+200x extreme points

- 2 x^{2} + 200 x

extreme f(x,y)=3x-1.5xy+0.5y^3 extreme points

f (x, y) = 3 x - 1.5 x y + 0.5 y^{3}
