The function V = f (t) = 36,000 - 4,500t, states that the value of a piece of equipment is a function of its age. V equals the value (in dollars) and t equal the age of equipment (in years). Determine the restricted domain and range for this function.

What set of values for t (age) make sense?
What set of values for V (value) make sense?
Mostly this will be a matter of whether each can be negative or zero; but draw a graph before thinking you're finished.
The answer may be partly subjective or contextual, as I can see slightly different answers being considered valid. But if this is from a math course, don't worry too much about what an accountant might say ...
