Given the following model: price=b0+ b1lotsize+b2lotsize^2 , how can one interpret the coefficients? Select the best answer.

A) A quadratic model does allow for an isolated interpretation of coefficients

B) Coefficients b1 and b2 cannot be interpreted individually because when lotsize increases by one unit, it is not possible or meaningful to keep the equation constant

C) A quadratic model does not allow for an isolated interpretation of coefficients

D) Coefficients can be interpreted individually because when lotsize is increased by one unit, it is possible to hold the equation constant
