Union and Intersection of Sets

Question

I need help figuring out how to find the Union or intersection of sets when provided with inequalities.

For example:
Find the intersection of sets {xlx<9},{xlx<-8}
Find the Union of sets {xlx<9}, {xlx<-8}

Thank you!

Answer 1

The intersection would be all values of x that is true for both statements and the union would be all values of x that is true for at least one of the statements.
