Determine whether or not the statement makes since and give a reason.

Scenario 1: I used a function to model data from 1980 though 2005. The independent variable in my model represented the number of years after 1980, so the function's domain was {x|x = 0, 1, 2, 3, ..., 25}.

Scenario 2: I have 2 functions. Function f models total world population x years after 2000, and function g models population of the world's more-developed regions x years after 2000. I can use f - g to determine the population of the world's less-developed regions for the years in both function's domains.
