C = 1: The graph starts out by going down steeply and levels out as it approaches 0.
C = 1.5: Again, the graph is steeply descending and levels out as it approaches .3.
C = 2: The graph is a straight horizontal line at .5.
C = 2.5: Now the graph goes up steeply, comes down a little, goes back up and levels at .6.
C = 3.4: "Mountains" are beginning to form. At this point the heights and widths of the mountains vary.
C = 3.8: This is a fairly uniform graph. The mountains have the same heights and widths.
C = 4: The graph starts at .5; it is steep and narrow to 1.0. After 1.0 it goes down and levels at 0 as it approaches 4.
