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

Time
(hour)
x

Velocity
(miles/hour)
y
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? (4 points)

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. (4 points)

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?

Can you fix the table for me first? it will be a lot easier

anonymous · Answer

x is the time of hour 
0, 1, 2, 3.
y is the velocity(miles/hours)
50, 52, 54, 56.

Righ i am back sorry

anonymous · Answer

The y intercept is the value of y when x=0, can you find that from the table?

anonymous · Answer

It shows that for every hour, you gain two miles. Yes.

Thanks for your help :) i got it now:)
