Textbook Value

The value of a certain textbook decreases according to the formula


V=45*20.9t
where V is the value of the textbook in dollars and t is the age of the textbook in years. What is the book worth when it is new? What is it worth when it is 2 years old? 10 years old? What is the domain and range of this function?

NOTE: Remember this is a model of a "real world" phenomenon. Don't approach such tasks with "blind mathematics". Consider the real world implications before setting down the answer(s).
