Example file with data, fit and chart.

The trendline equation of an exponential regression represented as follows: "f(x)=exp(-3608.77true0.09x)". It should read: "f(x)=exp(-3608.77)*exp(0.09x)".

The string has been "f(x)=exp(-3608.77 + 0.09x)" in former versions and is now broken for some reason. Nevertheless, when fixing it, a change to your form would be good, because it is nearer to the usual y=a*e^{bx}.
