In the year 2006, the average cost to rent a car was $\$39$ for the first day and an additional $\$23$ for each additional day.

1. Graph the relationship between cost and the duration of a car rental in 2006.

   Hint (a):

   If you rent a car for half a day, three-quarters of a day, or a full day, you pay the same rate. What kind of graph is this?

   More Help (a):

   For $1.5$ days, $1.75$ days, or $2$ days you will pay $\$39$ for the first day and $\$23$ for the second, even if you are just late bringing the car back by an hour.

   Answer (a):

   

2. Describe how the graph would be transformed if the current average cost of a car rental has increased to $\$50$ for the first day.

   Hint (b):

   If you don't remember what it means to transform a graph you can look it up in the glossary.
