Solving Compound Disjunction Inequalities on a Number Line

The video tutorial explains how to solve compound disjunction inequalities in one variable by graphing on a number line. It covers the use of open and closed circles to indicate whether a number is included in the solution set. The tutorial describes 'or' inequalities, where solutions lie along one arrow or the other on the number line. An example is provided to demonstrate solving and graphing these inequalities. Additionally, a real-world application involving a cross-country team tryout is discussed, illustrating how to apply these concepts practically.
