The table below represents the distance of an airplane from its destination as a function of time:


Time
(hours)
x Distance
(miles)
y
0 2,700
1 2,160
2 1,620
3 1,080
4 540


Part A: What is the y-intercept of the function, and what does this tell you about the airplane? (4 points)

Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 4 hours, and tell what the average rate represents. (4 points)

Part C: What would be the domain of the function if the airplane continued to travel at this rate until it reached its destination? (2 points)
