Question

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

Table:
Time Velocity
(hour) (miles/hour)
x y
0 50
1 52
2 54
3 56

Part 1: What is the y-intercept of the function, and what does this tell you about the car?

Part 2: Calculate the average rate of change of the functino represented by the table between x=1 to x=3 hours, and what does the average rate represent?

Answer 1

Part 3: 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?

Answer 2

@mathstudent55 @zepdrix @Nurali @Compassionate @hba Anyone, please help me! D:

Answer 3

Part 1: What is the y-intercept of the function, and what does this tell you about the car?

The y-intercept: y = 2, it tells us that, for every hour, we gain two miles.

1 52
2 54
3 56

The average rate of change is two miles per-hour. It represents acceleration/time.

Answer 4

Oh, okay. Thank you! Do you have any idea how to complete the other two parts? I don't. .-.

Answer 5

> Part 3: 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?

1 52
2 54
3 56

4 = 58
5 = 60

(5, 60), domain = 5, and range = 60.

Answer 6

Thank you so much!

Answer 7

No problem.
