graphing

[VincentsEcho]

In most businesses, increasing prices of their product can have a negative effect on the number of customers of the business. A bus company in a small town has an average number of riders of 1,000 per day. The bus company charges $2.00 for a ride. They conducted a survey of their customers and found that they will lose approximately 50 customers per day for each $.25 increase in fare.

Given the descriptions above, graph the function, identify the graph of the function (line, parabola, hyperbola, or exponential), explain your choice, and give the domain and range of the function.

I am at a loss on what goes where, so I am unable to make a graph, when I dont even know where to place the plots. Can anyone help me understand this?

Try the number of customers per day being the function in terms of the fare price.

When the price is $2, the number of customers per day is $1000.

When the price is $2.25, the number of customers per day is $950.

And so forth.

Tabulate:

     x    |   f(x)
  --------+---------
     2    |   1000
    2.25  |    950
          |
          |
          |
          |
          |

where f(x) is the number of customers per day,
x is the fare price.

Graphing should make things clear from there.
