Answer:
A domain is the possible x-values in a ordered pair or an input value in a table
Explanation:
I learned this by reading a lesson about it.
Also, here are some additional tips given from me to any of you when writing a domain or range!
When you write a domain or range:
1. List the numbers separated by commas instead of braces (if it is listed in braces and not in a table or ordered pair)
2. List the value(s) from least to greatest
Note: Duplicate numbers listed in an table or braces should only be listed once.
Hope this helps!
