a.
To graph: The given function on the domain
In the year 2003, the most CD singles were sold.
Given information:
From
Calculation:
Upon graphing the given function, the required graph would look like as shown below:
It is visible that the maximum volume occurs when
Therefore, the most CD singles were sold in 2003.
b.
To determine: Do you think that sales will continue to follow the model indefinitely? Explain your reasoning.
The sales will follow the model in the long run.
Given information:
From
Explanation:
From the graph in part (a), it is visible that the function is increasing without bound as x approaches towards positive infinity. But practically it is not possible as new technologies may replace CD singles.
Therefore, the sales will continue to follow the model indefinitely.
