16-9. Use the methodology of the preceding exercise and the accompanying data set given here to estimate the parameters β0 and β1 of the expression Y = eβ0+β1X,Y > 0, where the vertical intercept is eβ0 . The slope of this function is positive (respectively, negative) if β1 > 0(respectively,<0).

And since β1 = (1/Y)(dY/dX), this function is alternatively referred to as the constant growth curve; that is, the proportionate rate of change in Y per unit change in X is the constant β1.
