Final answer:
In this situation, the range is C>0 and the domain is m>=0.
Step-by-step explanation:
In this situation, the range and domain have limitations.
The domain represents the possible inputs or values for the number of miles driven. Since the Porter family is on a trip, it is reasonable to assume that they will drive at least some miles. Therefore, the domain in this situation is m>0, meaning the number of miles driven must be greater than zero.
The range, on the other hand, represents the possible outputs or costs. In this situation, the rental cost is $125 plus $0.30 per mile. Since the rental cost cannot be negative, the range is C>0.
Therefore, the correct answer is c) The domain is m>=0, and the range is C>0.
