Let *x* be the number

Observe the graph: a circle marked on the graph. So,

the points are not included in the set.

The number *x* is less than and greater than 1.

The distance between *x* and 0 is 1 unit.

The solution set is

The absolute value of a number is its distance from 0 on the number line.

So, the absolute value inequality for the graph is

The absolute value inequality for the graph is .
