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

Time
(hours)
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: What is the average rate of change of the function represented by the table between x = 0 to x = 2? What does this 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)

A. So for part A you can figure out that the car is traveling at 50 miles an hour because after every hour the distance decreases by 50.

anonymous · Answer

B. So for b the average change is 100 miles for every 2 hours, which can be simplified back to 50mph which represents the speed of the car.

C.  {y=-50x+900| (0,900),...(18,0) the domain is 18
