39+ Interval Notation Union Symbol
Photos. Determine the interval notation after graphing the solution set on a number line. For example, we can express the set, {x | x ≠ 0}, using interval notation as we can visualize the above union of intervals using a number line as, notice that on our number line, an open dot indicates exclusion of a point, a closed dot indicates inclusion of.

My comment is to suggest that the formulation you ask about causes unnecessary trouble by trying to use symbols rather than words to describe the answer. To indicate that one of the endpoints is to be excluded from the set, the corresponding square bracket can be either given 2 intervals, the two major relations between them are their union and their intersection. In interval notation we just write the beginning and ending numbers of the interval, and use we just saw how to join two sets using union (and the symbol ∪ ).
For each of the following exercises find the implicit domain of the function.
To indicate that one of the endpoints is to be excluded from the set, the corresponding square bracket can be either given 2 intervals, the two major relations between them are their union and their intersection. List of set symbols of set theory and probability. The numbers are the endpoints of the interval. Set notation & interval notation.
