The answer to your question is:

Domain [0, 30]

Range [0, 150]

Step-by-step explanation:

Data

Price = $150

decreased $5/month

V (t) value in dollars

The function will be V (t) = - 5t + 150 When V (0), t = 30 months

The graph is below

Domain [0, 30] I got them from the graph

Range [0, 150]
