- 2.7: Introduction to Inequalities and Interval Notation
Learn how to use interval notation to express subsets of real numbers on a number line. See how to convert inequalities to interval notation and graph them using different symbols and types of intervals.
Learn how to define and represent intervals using inequalities, the number line and interval notation. See examples, symbols and tips for union, intersection and exclusion of endpoints.
Learn how to use interval notation to denote all the numbers between a given set of numbers. Find out the meaning of brackets, parenthesis, union, intersection, and infinity symbols, and how to convert inequalities to intervals.
So an interval notation is simply a compact way of representing subsets of real numbers using two numbers (left and right endpoints), the comma symbol, parentheses ( ), brackets [ ], and infinity symbols (positive or negative).
Compare interval notation with set-builder notation. Share an example of a set described using both systems. Explain why we do not use a bracket in interval notation when infinity is an endpoint. Research and discuss the different compound inequalities, particularly unions and intersections. Research and discuss the history of infinity.
Learn how to write and interpret interval notation, a way to describe continuous sets of real numbers by the numbers that bound them. See examples, symbols, and alternate notations for open, closed, and union intervals.
