Final answer:
To determine the domain and range of a function based on the given graph, we need to look at the x-values and y-values that the graph covers. The domain of the function is [3, 4] and the range is [0, 4].
Step-by-step explanation:
To determine the domain and range of a function based on the given graph, we need to look at the x-values and y-values that the graph covers. From the graph, we can see that the x-values range from 3 to 4, inclusive. Therefore, the domain is [3, 4]. As for the y-values, we can see that they range from 0 to 4, inclusive. Hence, the range is [0, 4]. Therefore, the correct answer is option D. Domain: [3, 4], Range: [0, 4].
