extreme sqrt(x)+sqrt(4-x)

extreme points

x + 4 - x

Minimum (0, 2), Maximum (2, 22), Minimum (4, 2)

Solution steps

f^{'} (x) = \frac{1}{2 x} - \frac{1}{2 4 - x}

Find intervals:

Increasing

: 0 < x < 2,

Decreasing

: 2 < x < 4

Plug

x = 0

into

x + 4 - x : 2

Minimum (0, 2)

Plug

x = 2

into

x + 4 - x : 22

Maximum (2, 22)

Plug

x = 4

into

x + 4 - x : 2

Minimum (4, 2)

Minimum (0, 2), Maximum (2, 22), Minimum (4, 2)

3 x - 1

f (x) = \frac{( 3 x + 6 )}{9}

f (x) = x^{2} - ln (x)

x + 3 - \frac{7 - x}{x}

2 x - 1
