We can also use desmos instead to find an exponential function that fits the data. This returns an equation of the form, y = abx (7.5.1) (7.5.1) y = a b x. Note that:How do you calculate exponential regression? First, you need to have data pairs of the form \((X_i, Y_i)\). Normally, when these data are at least loosely clustered around a straight line, a linear regression model is calculated by computing its coefficients via the Least Squares method.
