Brackets are used when the answer is included, and parenthesis are used when the answer is excluded. Interval notation goes from least to greatest. This means that any number from 6 to ∞ is an answer, including 6 and excluding ∞ .Interval notation · Intervals are noted in various ways depending on the characteristics of their two endpoints (a and b), which is what we call interval ...
If two or more intervals are interrupted with a gap in the number line, set notation is used to stitch the intervals together, symbolically.
