Exponential regression calculator.
Your data are far away to be exponential distributed. You get for the x-values 7 and 20 the y-value 10 and for the x-value 15 the y-value 1. How on earth you can think that there is a trend in your data ? You have to choose data with an (exponential) trend. Please make an edit of your question. $\endgroup$ –
