The graph is a bit like (sorry, I can't find a pic of it on the net I've only seen it on paper) a cross between y=e^x and y=-e^x (I think this reflects the original y=e^x in the y axis) but if you take away the lines that keep going up, you have an almost straight line with a lump in the middle where it crosses the y axis and the line never touches 0 (I don't think it does anyway). What's the equation of the graph?
Thanks for any help!
This sounds a bit like a bell shaped curve - otherwise called a normal or gaussian distribution. This is a very important graph in statistics.
Take a look at this graph. The graph and the formulas are here, as well as an explanation. Please let me know if this is it.

Almost. But the graph I've seen is much flatter and the bump in the middle is small but quite sudden and crosses the y axis at (0,0.5). Is there any to modify the equation of the graph on that site to match the graph I'm talking about?
