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.

Determine that linear model, e.g., with the method of least squares. Transform the data along with the model back to the original form. Exponential regression formula for the data (x, y) is: y = exp (c) * exp (m * x) Where m is the slope and c is the intercept of the linear regression model fitted to the data (x, ln (y)).
