the table below represents the distance of a train from its destination as a function of time:
time (hours) x distance (miles) y
0 665
1 570
2 475
3 380
4 285
part a: what is the y-intercept of the function, and what does this tell you about the train?
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.
part c: what would be the domain of the function if the train continued to travel at this rate until it reached its destination?
