Exponential regression calculator.
My goal is to fit these data with an exponential regression model and to print the exponential regression equation and R2 on the graph. The coefficients in the plot don't fit the plotted line. You need to use exp.mod <- lm (y ~ poly (x, 2, raw = TRUE), df). @Roland it seems that's not what the OP wanted anyway.

Exponential regression is a type of regression that can be used to model the following situations: 1. Exponential growth: Growth begins slowly and then accelerates rapidly without bound. 2.
