The function seems to be accurate till
Explanation of Solution
Given information:
The given equation is
Calculation:
As there are many other form of media in the market today. CD will not increase any more. That means the sales of CD will not increase any more. That means the sales of the CD will decrease.
Therefore, the function seems to be accurate till
