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.
Which quadratic function best fits this data? x y 1 32 2 78 3 178 4 326 5 390 6 337 a. y=11.41x2+154.42x−143.9 b. y=−11.41x2+154.42x−143.9 c. y=11.41x2+154.42x+143.9 d. y=−11.41x2+154.42x+143.9
