all real numbers at least -3 and at most -1.

There are three ways to express this.

1.  It can be expressed with this number line graph

-7  -6  -5  -4  -3  -2  -1   0   1   2   3   4 

2.  It can be expressed with this set-builder notation

             {x|-3 ≦ x ≦ -1}

3.  It can be expressed with this interval notation:

                [-3, -1]
