Question

Math check please!

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

Answer: The y-intercept is 50. This tells us that the cars miles/ hour starts at 50 and goes up 2 more for each additional hour.

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.

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

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

Answer: The y-intercept is 50. This tells us that the cars miles/ hour starts at 50 and goes up 2 more for each additional hour.

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.

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

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?

Answer: The Domain would be 5 and the range would be 60.

Answer 2

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

Answer 3

Part C is correct
Part B is correct except that the rate of change is 2 miles per hour per hour (2 m ^h-2) which represents acceleration ( rate of change of velocity).
