A sequence X is define as numbers smaller than 10 that are divisible by 2 and a natural number. What are the domain and ranges?
I assume that the domain and range here is:
dom X = <1,2,3,4,5,6,7,8,9> ran X = <2,4,6,8>
I'm not sure if this is correct, can anyone verify? Especially the dom X part, i'm not sure about that.
