I'm too lazy right now, but have you tried plotting it?

anonymous · Answer

no

anonymous · Answer

I don't think it's any of them, but it's late and I'm guessing.

anonymous · Answer

ok

anonymous · Answer

Direct, do you concur?

anonymous · Answer

oh I was asking the guy who's viewing this

anonymous · Answer

Well it's not quadratic b/c the y-values for x=-2 and x=0 have to be the same... and they're not.  Obviously not linear.  Not exp either.

I'm downloading Java so that I can use the online point plotter to see how the data looks. I could have plotted the data by hand in the time it took to find a plotter and then to download Java. So, I was not looking at this screen but have just returned to get the points.

I concur. The point-plotter is such that you can't see any more than the hole through which you are looking.
