Compound Inequalities - Special Cases

Here is a quick reteaching video that may clear up some questions on the SPECIAL CASE problems such as NO SOLUTION  and ALL REAL NUMBERS. 

Remember that it is possible that OR compound inequalities or GREATOR absolute value inequalities may produce a solution of ALL REAL NUMBERS.

Remember that it is possible that AND compound inequalities of Less ThAND absolute value inequalities may produce a solution of NO SOLUTION.
