extreme f(x)=x+(17)/x

extreme points

f (x) = x + \frac{17}{x}

Maximum (- 17, - 217), Minimum (17, 217)

Solution steps

f^{'} (x) = 1 - \frac{17}{x ^{2}}

Find intervals:

Increasing

: - \infty < x < - 17,

Decreasing

: - 17 < x < 0,

Decreasing

: 0 < x < 17,

Increasing

: 17 < x < \infty

Plug

x = - 17

into

x + \frac{17}{x} : - 217

Maximum (- 17, - 217)

Plug

x = 17

into

x + \frac{17}{x} : 217

Minimum (17, 217)

Maximum (- 17, - 217), Minimum (17, 217)

(8, 6), (- 4, - 3)

f (x) = \frac{- x ^{2} - 5 x + 2}{x + 3}

2 sin (\frac{1}{2})

x - 5

- x + y = 4
