HELP PLEASE !!!
The table below represents the velocity of a car as a function of time:

Time=X
(hour)
Velocity=Y
(miles/hours)
0 50
1 52
2 54
3 56

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 tell what the average rate represents.

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?
