We want to determine the domain and range in the given situation, we will get that the domain is time in days, while the range is the number of calories consumed.
For a function y = f(x), we define the domain as the set of the possible inputs, while the range is the set of the outputs.
In this situation, we know that in average, the number of calories consumed per day are around 2000 cal.
So we have a relation between calories consumed and time.
We can define the independent variable (input) as the time in days, then the domain can be {0 days, 1 day, 2 days, 3 days, ...} any integer number of days.
On the other hand, the range is also an integer number that depends on the number of days, assuming you burn 2000 cal per day, the range will be: {0cal, 2000 cal, 4000 cal, 6000 cal, ...}
