I need to do exponential regression on these values:

 

x    2008       2009       2010       2011   
y    0.48       1.08    2.84    7.16

 

 

 

I can calculate a:

 

 

But when I try to calculate b I get an error.

 

 

I found out that this is due to a^x1 being so small a number that it would round to zero, making the divide impossible. How do I go about calculating this, is there are smarter way to do the regression?

I would suggest trying it over, but change your x-values to  8, 9, 10, 11.
