Final answer:
At time t=0, the number of DVDs in your collection is 8.
Step-by-step explanation:
The statement an(0) = 8 means that at time t = 0, the number of DVDs in your collection is 8. The function n(t) represents the number of DVDs in your collection after trips to the video store, and a represents a specific value of n(t) at a given time. In this case, the value of n(t) is 8 at time t = 0.
