Answer:
The number of copies can be any number greater than or equal to 1.
Explanation:
Remove the descriptions involving costs because that explains the <em>range</em> of the graph and not the <em>domain</em>.
The number of copies can be either 1, 2, 3, 4, 5, 6, or 7.
This description is false. There are an unlimited amount of copies you can make and not only up to 7 copies. Other wise the graph would end at x = 7.
Speaking of unlimited, the last choice is correct because you can get 1 copy or more than 1.
