Final answer:
The domain of the number 8 is the set of all whole numbers. The range of the number 8 is the number 8 itself.
Step-by-step explanation:
The domain of a number is the set of all possible values that the number can take.
Since the number 8 is a whole number, its domain is the set of all whole numbers.
The range of a number is the set of all possible values that can result from using the number in a specific situation.
Since the number 8 is a single value, its range would be just the number 8 itself.
