Analyze the demand function :Q_L= 3536 - .5P_L+ .2P_C+ .008I + .0001A

1.Characterize this function by circling all in the following list that are applicable:

univariate, bivariate, multivariate, linear, exponential, logarithmic, curvilinear, 1^st degree, 2^nd degree, 3^rd degree, additive, multiplicative, linearly homogeneous

2.What is the numerical value of the partial derivative of the function with respect to income (be sure to also include the + or - sign.Note: I do not want the symbol for this partial derivative)?

3.Write the mathematical symbol representing the coefficient of advertising (the numerical value of this coefficient is +.0001, but the answer you give is to be the representing this partial derivative).

4.Assuming there is a $200 increase in the price of Paradise Lake lots (P_L), what change in quantity demanded of Paradise Lake lots will result (give the numerical value of it, too).

5. Are Paradise Lake lots a normal or an inferior good?What feature of the function tells you?

6.Explain in words what the intercept (which is 3536) includes (or does not include).

7.Is there a direct or is there an inverse relationship between demand for lots (Q_L) and advertising expenditures (A)?What feature of the function tells you?

8.How will demand for Paradise Lake's lots (Q_L) change in response to a $1000 decrease in the price of competing lots (P_c) (give the numerical value of it, too)?

9.How will demand for Paradise Lake's lots change in response to a $1000 decrease in income (I) (give the numerical value of it, too)?

10.What variable do I need to change in order to achieve a change in the quantity demanded (Q_L) of Paradise Lake lots?
