Final answer:
The student's question involves finding the relevant domain and range of an exponential decay function representing the daily views of an internet video. The domain is the first 10 days, and the range is determined by calculating the function's output for each day within the domain.
Step-by-step explanation:
The question refers to an exponential decay function representing the number of daily views for a video posted online. The function given is y = 20(0.8x), where x is the number of days since the video was released, and y is the number of daily views in thousands. To identify the relevant domain and range, we consider the context of the problem. The domain refers to the number of days, which is the first 10 days, so the domain is {1, 2, 3, ..., 10}. The range is the set of possible values for y, which depends on the function values from x = 1 to x = 10, after calculating and rounding if necessary.
