Consider the nonlinear relationship shown by equation E(y] = ,Su\"l'. Use logarithms to develop an estimated regression equation for this model. log(Price) = : + \\:I log(Rating) (to 3 decimals) What is the value of the coefficient of determination?

Explain. The model in part @ is preferred because it provides a better fit
