Answer: Check out the diagram below for the filled out table
Explanation:
Use square brackets to include the endpoint. A curved parenthesis is used to exclude the endpoint. This is to set up the interval notation.
So for example, writing [a,b] means [tex]a \le x \le b[/tex]
Another example: writing (a, b] means [tex]a < x \le b[/tex]
The set notation is practically identical to the inequality notation. All that's new is the use of surrounding curly braces, and the x | up front. In my opinion, the third column seems a bit redundant.
