What is the solution set of {x | x > -5} {x | x < 5}?

Question

A. the empty set
B. the numbers between -5 and 5
C. all numbers except -5 and 5
D. all real numbers

Answer 1

plot the intervals on the number line
If the solution set is {x | x > -5} AND {x | x < 5}
-5 < x < 5

If it is {x | x > -5} OR {x | x < 5}
then it is the whole number line.
