x & gt-2

(2) 4x+2≤3x+3

x≤ 1

Then that solution of this inequality is -2.

Divide this solution into two parts

x+3 & gt； 0

X-0.5≤0 inch -2

x-0.5 & gt； 0 is in 0.5

Maximum value:

The maximum value of |x-0.5| is -2.

And the maximum value of |x+3| is 0.5.

Because 3 & gt0.5, the maximum value is 0.5.

The value is 1

The maximum value is 4.5

Minimum value: The minimum value of x-0.5| is -2.

And the minimum value of |x+3| is -2.

When X =-3, X+3 = 0.

When X = 0.5, X-0.5 = 0.

When the value is in the middle of (-3,0.5), that is, (0.5-3)/2 =- 1.25 is the minimum value.

The minimum value is 3.5 (in fact, this formula is in -2
