Thats the problem I am having, I can't remember how a problem would look, but I know for a fact there is a type of math that uses this.

you could be referring to interval notation when displaying a set of numbers?

for example for the function f(x), the domain could be D: xe[0,12)U[15,1000)xeR?

Absolutely right, it is definitely interval notation thank you.
