To solve inequalities, isolate the variable on one side of the inequality, If … WebThe square brackets tells you that the end values are included in the interval. If you have an inequality like: -2≤x<5, then the interval notation is: [-2, 5) A square bracket is on the -2 because it is included in the interval. The 5 gets a parentheses because it is not in the interval. Hope this helps. WebInterval notation is a way to write all of the values bound by end points.
