hey,

I was wondering if anyone could explain how you can calculate the function of a graph with the given points, specifically an exponential function! Are there any step by step guides to do this. Tried searching google but they all require you to know the function to plot it! Although if there are any other guides like calculating polynomial or logarithmic functions I would like these also. Many may suggest just to use a calculator however I need to do this by hand, I can then verify this using a calculator which I can do already!

Thanks :)
