Hi,

I have some data (x,y) and I plotted its graph in excel, and added a trendline which is defined by

$\displaystyle y = c*exp(x)$

but my claim was $\displaystyle y = c * 2^x$ and I don't know how to make the line equation power of 2 instead of e.

So, does this (exp) equation implies that my claim was true?

I mean is it sufficient to show $\displaystyle y = c * (some\_base)^x$?
