Imagine yourself folding a paper in half. And then again folding it in half, and then again and again until you reach the moon! How many times would you have to fold the paper?
Does the thickness of the paper matter?
Look at the graphs below and their respective table of values. X represents the number of folds and Y represents the distance you get from the fold. If the moon is 3.86 * 10^10 cm away how many folds does it take to get there using cash register tape? How about using card stock?
What does y represent when x=0? What type of functions are these? How do you know?
