Thread: Can I change the base number in y=c*b^x ?

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

but my claim was 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 ?

Hey publicvoid.

Recall that (e^ln(a))^x = a^x = e^(x*ln(a)) so using a substitution z = x*ln(a) you can get a^x by using f(z) = e^z where z = x*ln(a).
