Find maximum of exponential equation created with CFTOOL?

Hello!
I need to find the maximum point of my data that i've extrapolated fitting it to an exponential-equation created by CFTOOL. Where y goes to infinity (I could also flip the data if it makes it easier). How can I do this the easiest way?

Are you looking for that value of x where your model would predict an infinite value? Sorry, but IF this is an exponential model, it NEVER reaches infinity.
The fact is, extrapolation of data to an asymptote at infinity is a perilous task. The specific model you choose will be the driver here, and you have not bothered to tell us that information.
Had you chosen a model that makes mechanistic, physical sense in the context of the physical system you are trying to model, this would be a bit different. But we have no indication this is true.
