The domain of \(V(n)\) is all whole numbers from 0 to 100.

Explicação

## Step 1<br />The problem involves the concept of functions and their domains. The function \(V(n)\) represents the volume of mouthwash remaining in the bottle after \(n\) uses. The domain of a function is the set of all possible input values (in this case, \(n\), which represents the number of uses) for which the function is defined.<br /><br />## Step 2<br />Rosanne has a 1,000-milliliter bottle of mouthwash and uses 10 milliliters each night. Therefore, the bottle will last for \(1000/10 = 100\) uses. This means that the function \(V(n)\) is defined for all whole numbers from 0 to 100, as the bottle will be empty after 100 uses.<br /><br />## Step 3<br />The other options are not correct because:<br />- The domain is not all whole numbers from 0 to 10, because the bottle will be empty before 10 uses.<br />- The domain is not all whole numbers, because the function is not defined for numbers greater than 100.<br />- The domain is not all whole numbers from 0 to 1,000, because the bottle will be empty before 1,000 uses.
