Final answer:
The domain is [3, ∞), and the range is [0, ∞).
Step-by-step explanation:
The domain in this context refers to the possible values for the amount of data used. Since the student has already used 3 GB of data and each time they stream their favorite Netflix show, they use another 2 GB of data, the domain would be any non-negative value greater than or equal to 3. In interval notation, the domain would be [3, ∞).
The range, on the other hand, refers to the values of data used. In this case, the range would be the amount of data used after streaming the Netflix show. Since each time they stream the show, they use 2 GB of data, the range would be any non-negative value greater than or equal to 0. In interval notation, the range would be [0, ∞).
