(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 horse continued to walk at this rate until it traveled 508 feet from the barn? (2 points)
