The cost of going to a movie theater increases annually. If it costs $7.83, with tax, to go to the movie theater in 2020, the function f (x) = 7.83(1.04) can be used to determine how much it will cost to go to the movie theater 2 years after 2020, where = 1 represents going to the movie theater during 2021.
Which best represents the domain of the function in this context?
all rational numbers
O all real numbers
O negative integers only
nonnegative integers only
