Question 340407
<font face="Garamond" size="+2">


Same idea as your question about the brackets and parentheses in interval notation.  If the endpoint is included as when you are dealing with *[tex \Large \leq] or *[tex \Large \geq], then you use a solid dot.  If the endpoint is NOT included, as when you are dealing with *[tex \Large <] or *[tex \Large >], then you use an open circle.


Summary:

If in Set Builder Notation or an Inequality you see *[tex \Large \leq] or *[tex \Large \geq], then in Interval Notation you use [ or ] and in graphing on the number line you use solid dots.


If in Set Builder Notation or an Inequality you see *[tex \Large <] or *[tex \Large >], then in Interval Notation you use ( or ) and in graphing on the number line you use open dots.
