Since to complete the table, we have the cost of each ticket.
That is one ticket
Therefore for total number of tickets we will multiply the ticket with
So the tabular form is mentioned below.
Now, domain of the relation is the set of all x -coordinates of number of tickets and range is the set of all y -coordinates of total cost.
Therefore, domain of the function of a table is
