Question 541801: When writing down a function and a domain, do the numbers in the set HAVE to be written in a certain order? Should they necessarily be written in order as on the number line? Ex: neg3, neg1, 3, 5
rather than 3, neg 1, 5, neg 3?

it makes them easier to see.
check with your instructor to see what your instructor requires.
it's still the right or wrong answer regardless of the order in which it is presented.
if you are doing online classes and entering into the computer, then it is the computer rules that need to be followed.
generally speaking, they are presented in order but i don't believe that's a hard and fast rule that's applied everywhere.
i have seen presentations online that sometimes show them in order and sometimes don't.
i have also seen tutorials online that sometimes show them in order and sometimes don't.
it's a good idea to try to do so.
it does make it easier to read them.
once again though, it's really up to your instructor and what he or she expects.
