Two sisters have decided to watch all the episodes of a popular TV show on DVD. Amy has already watched 12 episodes and will continue to watch the show at a rate of 2 episodes per day. Jenny, who hasn't yet seen the show, will start watching 4 episodes per day. Once the two sisters get to the point where they have watched the same number of episodes, they plan to finish the series together. How many episodes will each sister have watched at that point? How long will that take?

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (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 fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
