If a set of paired data gives the indication that the regression equation is of the form µY|x = α ∙ βx, it is customary to estimate a and β by fitting the line

to the points {(xi, logyi); i = 1, 2, . . . , n} by the method of least squares. Use this technique to fit an exponential curve of the form = ∙ β^x to the following data on the growth of cactus grafts under controlled environmental conditions:
