A new car worth $48,000 is depreciating in value by $6000 per year. The mathematical model, which describes the car's value, y, in dollars, after x years, is y = -6000x + 48,000. a. Find the x-intercept. Describe what this means in terms of the car's value. b. Find the y-intercept. Describe what this means in terms of the car's value. c. Use the intercepts to graph the linear equation. Because x and y must be nonnegative, limit your graph to quadrant I and its boundaries. d. Use your graph to estimate the car's value after five years. a. The x-intercept is (Type an integer or a fraction.) Describe what this means in terms of the car's value. Choose the correct answer below. O A. After 8 years, the car is worth $0 less than it was worth when it was new. OB. The car has no value after 8 years. OC. The car is worth $8 after 8 years. O D. After 1 year, the car is worth $8 less than it was worth when it was new. b. The y-intercept is (Type an integer or a fraction.) Choose the statement that best describes the significance of the y-intercept. OA. The value of the car is never less than $48,000. OB. The car is worth $48,000 less than it was worth when it was new. OC. The original value of the car is $48,000.
