On the number line diagram, heavy arrow drawn from – 1 to left side and 3 to right

side. So, the

numbers below –1 and above 3 are solutions to the inequality.

On the number line diagram a circle is shown at – 1 and 3. So, the numbers – 1 and

3 are not included in the solution set.

So, the solution set is .

To write a open sentence, find the point that is same distance from points – 1 and 3.

The distance from – 1 to 1 is 2 units.

The distance from 1 to 3 is 2 units.

Since the midpoint is 1.

The distance between 1 and x is greater than or equal to 2 units.

So, the open sentence for the given graph is

Open sentence for the given graph is .
