Answer:
all whole numbers
all whole-number multiples of 125
Step-by-step explanation:

The domain and the range of a function is the set of input and output values of the function.
- The domain is the set of all whole numbers
- The range is the set of all whole numbers
Let the number of tickets be x, and the revenue be y.
So, the revenue function will be:
[tex]\mathbf{y = 125x}[/tex]
The number of tickets cannot be less than 0.
So, the domain of the revenue function is:
[tex]\mathbf{Domain = [0,\infty)}[/tex]
The above means that, the domain is the set of all whole numbers
Similarly, the revenue cannot be less than 0.
So, the range of the revenue function is:
[tex]\mathbf{Range = [0,\infty)}[/tex]
The above means that, the range is also the set of all whole numbers (in multiples of 125)
