It is denoted by symbol ꓴ. This symbol is used when the sets are expressed in interval notation. In the example below, we have two sets. First set A denoted by the blue line has elem ents between 4 and 6 while the second set in red has elements between 8 and 12.

WebFor example, the infinite interval containing all points greater than or equal to 6 is expressed [6,Inf). If the set includes more than one interval, they are joined using the union symbol U. For example, the set consisting of all points in (-3,7] together with all points in [-8,-5) is expressed [-8,-5)U(-3,7]. WebQuadratic inequalities can have infinitely many solutions, one solution, or no solution. If there are infinitely many solutions, graph the solution set on a number line and/or express the solution using interval notation.
