The table below represents the velocity of a car as a function of time:
Time
(hour)
x Velocity
(miles/hours)
y
0 50
1 52
2 54
3 56
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 hours, and tell what the average rate represents. (4 points)
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?
Part A. y-intercept tells about how much velocity does car reaches in a certain time. Part B. the average rate of change is = x+1,y+2 Part C. Car reaches 60 miles per hour of velocity in 5 hours.
