If the number line graph is

<=====================o---------------
-5 -4 -3 -2 -1  0  1  2  3  4  5  6  7

the interval notation is {{{(matrix(1,3,-infinity,",",2))}}}

If the number line graph is

-------------------&#9787;=================>
-5 -4 -3 -2 -1  0  1  2  3  4  5  6  7

the interval notation is {{{(matrix(1,3,1,",",infinity))}}}

If the number line graph goes:

1. all the way to the left from point A, including A is (-&#8734;,A]
2. all the way to the left from point A, not including A is (-&#8734;,A)
3. all the way to the right from point A, including A is [A,&#8734;)
4. all the way to the right from point A, not including A is (A,&#8734;)
