extreme (18)/x+3x^2

Solution

extreme points

\frac{18}{x} + 3 x^{2}

Solution

Solution steps

f^{'} (x) = - \frac{18}{x ^{2}} + 6 x

Find intervals:

Decreasing

: - \infty < x < 0,

Decreasing

Increasing

Plug

into

\frac{18}{x} + 3 x^{2} : 9 \cdot 3^{\frac{2}{3}}

Popular Examples

extreme f(x)=3x^2-4x+12 extreme points

f (x) = 3 x^{2} - 4 x + 12

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

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

extreme f(x,y)=2x^2+3y^2+2xy-6x-8y+11 extreme points

f (x, y) = 2 x^{2} + 3 y^{2} + 2 x y - 6 x - 8 y + 11

extreme f(x,y)=x^2-2xy+1/3 y^3-4y extreme points

f (x, y) = x^{2} - 2 x y + \frac{1}{3} y^{3} - 4 y

extreme f(x)=4x^5-25x^4+40x^3-4[-1.4]extreme points

f (x) = 4 x^{5} - 25 x^{4} + 40 x^{3} - 4 [- 1.4]
