I will refer to the graphs as 1 - 6, starting at the top and going down. 6 is not present, though I will still include it by process of elimination.
All real numbers less than -7 or odd numbers between -7 and 7, exclusive. = Graph #6
All real numbers except -7. = Graph #2
Numbers divisible by 4 between -10 and 10. = Graph #4
All real numbers up to and including -1 or more than 1. = Graph #1
All real numbers between -7 and -4, inclusive, or between -1 and 1, exclusive. = Graph #3
Prime numbers between -10 and 10. = Graph #5
Hope this helps!
