Part A: What is the y-intercept of the function and what does this tell you about the car? Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours and what does the average rate represent? Part C: What would be the domain of the function if the velocity of the car was measured until it reached 60 miles/hour and the car does not change motion?

The table below represents the velocity of a car as a function of time.

Time(hour)|Velocity(miles/hour)
     x                  y
0                      50
1                      52
2                      54
3                      56

The car is accelerating 2 mph per hour, having started with a velocity of 50 mph. Acceleration between hours 1 and 3 is the change in velocity divided by (3-1) = 2 hrs.
