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 yintercept 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)

What is your question about how to do this?
