(a)
Explanation of Solution
Given:
The number of people who watch a singing competition can be given by
Concept Used:
Make a table of values for the points
The domain is all real numbers, so there are infinitely many solutions. Select values from the domain and make a table.
Calculation:
The domain is all real numbers, so there are infinitely many solutions. Select values from the domain and make a table.

4 | (4, 6) | |
6 | (6, 9) | |
8 | (8, 12) | |
10 | (10, 15) |
Thus, the domain is all real numbers, so there are infinitely many solutions.
(b)

Answer to Problem 35PPS
If there are 14 million potential viewers, there will about 21 million people who watch.
Explanation of Solution
Given:
The number of people who watch a singing competition can be given by
Concept Used:
Use the graph to eastimate the number of people who saw if there are 14 million potential viewers
Calculation:
Using the graph, where there are 14 million potential viewers, there will about 21 million people who watch.
Number of people in millions who saw the show is 21 million where there are 14 million potential viewers.
Thus, number of people in millions who saw the show is 21 million where there are 14 million potential viewers.
(d)
Explain why it would not make sense for v to a negative number.
(d)
Answer to Problem 35PPS
A negative does not make sense because you cannot have a negative number of viewers.
Explanation of Solution
Given:
The number of people who watch a singing competition can be given by
Concept Used:
A negative does not make sense because you cannot have a negative number of viewers.
