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: calculate the average rate of change of the function represented by the table between x = 1 to x = 3, and tell what the average rate represents. (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)
