In set builder notation, “x|x” signifies “x such that x.” When graphing, it’s utilised to create lists of numbers and define domains.
Between the curly brackets that start and conclude a set, the word “x|x” is used. The first x is followed by a qualifier that narrows the set, such as “less than” or “greater than” a particular amount. For instance, the set of all x that are less than 5 can be expressed as x|x5. The variable x in “x|x” can be substituted with any letter (x|x, a|a, b|b, and c|c all imply the same thing), and the middle bar can be replaced with a: sign (x:x is the same as x|x).
