Essential question-how can I explore patterns in the real world? ** A. ** **Use your graphing calculator to graph each question below. Adjust the window settings until you thing you have a good view of the graph. Copy the graph onto your paper. (**answer in process) y=(x-1) (5-x) Shelly is on a submarine. The submarine is floating on the water, 15 more people get on that submarine. It can only hold 3 people. The submarine is getting heavier. At a point the submarine sinks.
