The table below represents the distance of a car from its destination as a function of time:
Time
(hours)
xDistance
(miles)
y
0900
1850
2800
3750
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, and tell what the average rate represents. (4 points)
Part C: What would be the domain of this function if the car traveled the same rate until it reached its destination?
