For each Compound Inequality listed below, identify 4 solutions and 4 nonsolutions.
If there are no solutions or the solution set includes all real numbers, write that instead of making a list.

Solutions for intersections, which use and will make both of the expressions
true
. 
Solutions for unions, which use or will make at least one of the expressions
true
.
Pay special attention to the numbers in the sample expression! Challenge yourself to use negatives, positives, fractions, decimals, etc. for your x
values.
The first two have been done for you  Answers will vary!
Expression  4 solutions that evaluate to true 
4 nonsolutions that evaluate to false

b 

All real numbers 
No nonsolutions

1 Could there ever be a union with no solutions? Explain your thinking.
2 Could there ever be an intersection whose solution is all real numbers? Explain your thinking.
