extreme f(x)=sqrt(x^2+81)

Solution

extreme points

f (x) = x^{2} + 81

Solution

Minimum (0, 9)

Solution steps

f^{'} (x) = \frac{x}{x ^{2} + 81}

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Plug

x = 0

into

x^{2} + 81 : 9

Minimum (0, 9)

Popular Examples

extreme f(x,y)= 414/23 x^{2/3}y^{1/3}extreme points

f (x, y) = \frac{414}{23} x^{\frac{2}{3}} y^{\frac{1}{3}}

extreme f(x)=5x-4ln(4x)extreme points

f (x) = 5 x - 4 ln (4 x)

extreme f(x)=x^4-3x^2=x^2(x^2-3)extreme points

f (x) = x^{4} - 3 x^{2} = x^{2} (x^{2} - 3)

extreme g(x,y)=x^3+y^3-3x-3y extreme points

g (x, y) = x^{3} + y^{3} - 3 x - 3 y

extreme f(x)=-x^6-3x^3+x+1 extreme points

f (x) = - x^{6} - 3 x^{3} + x + 1
