extreme f(x)=x^2+(54)/x

Solution

extreme points

f (x) = x^{2} + \frac{54}{x}

Solution

Minimum (3, 27)

Solution steps

f^{'} (x) = 2 x - \frac{54}{x ^{2}}

Find intervals:

Decreasing

: - \infty < x < 0,

Decreasing

: 0 < x < 3,

Increasing

: 3 < x < \infty

Plug

x = 3

into

x^{2} + \frac{54}{x} : 27

Minimum (3, 27)

Popular Examples

line y=2-3x line

y = 2 - 3 x

domain of f(x)=(x+3)/(x^2+3x+2)domain

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

simplify (2.1)(-3.6)simplify

(2.1) (- 3.6)

slope ofintercept 6y-8x=54 slope intercept

6 y - 8 x = 54

domain of f(x)=sqrt(x-1)+sqrt(2-x)domain

f (x) = x - 1 + 2 - x
