EXTRA CREDIT: This question is for bonus points only. (12 points) A new car initially cost $27,000 and depreciates (loses value by) $1500 every year. Its value, , can be modeled as a linear function based on age. (a) What does the independent variable represent? What does the dependent variable represent? (b) Write the linear function modeling the value of the car. (c) Use the function from part (b) to algebraically determine the value after 6 years. Report your answer with appropriate units. (d) Use the function from part (b) to algebraically determine when the car will be worth $10,500. Report your answer with appropriate units. (e) Graph . Select a scale and label your axes so that the value of the machine can be graphed from its original time of purchase until the year when its value becomes zero.
