Question

The table below represents the distance of a car from its destination as a function of time.


Time
(hour)
x
Distance (miles)
y
0
900
1
850
2
800
3
750


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 what does the average rate represent? (4 points)

Part C: What would be the domain of this function if the car traveled the same rate until it reached its destination? (2 points)

Answer 1

Part A: The y-intercept is 900, it tells you that the car was already going 900 miles at 0 hours

Answer 2

Part B: do this by yourself, it's easy

850 - 900/ 3 - 1
