How to write interval notation.
With inequalities, we use "less than or equal to": ≤ or "greater than or equal to": ≥ to include the endpoint of the interval. With interval notation, we use use square brackets, [ or ]. To combine two intervals, use U (an uppercase letter u) for union: ∪ ∪. Use oo (two lowercase letter o's) for infinity: ∞ ∞.
Intervals are a great way to improve your speed and endurance for running, but what should you do between those intervals: walk or jog? It turns out the answer depends on your goal... Some General Tips. The smaller value of the interval goes first and the larger value of the interval goes second; the two values are separated by a comma. Parentheses indicate an open interval and square brackets a closed interval, although you can also have a mixture of the two, giving a half closed or half open interval. For example: The correct notation for a set with only the point 3 3 in it is {3} { 3 }. If you really want to use interval notation, you could also denote this as [3, 3] [ 3, 3]. Notice that your solution set is just (2, ∞) ( 2, ∞) though, since 3 3 is already in the set (2, ∞) ( 2, ∞).
