Слайд 7The Mathematics of Demand Functions
Indirect demand functions
Gives price as a function
of quantity, not the other way around.
We can always restate indirect demand functions as direct demand functions and vice versa.

Слайд 8The Mathematics of Demand Functions
A Graphical Interpretation
Knowing price we know quantity
demanded.

Слайд 15The Mathematics of Demand Functions
An Example
2P = 100 – Q
(1/2)[2P] =
(1/2)[100-Q]
P = 50 – (1/2)Q
P = 50 – (1/2)Q
Слайд 17The Mathematics of Demand Functions
A Second Example
P = 50 – (1/2)Q
2P
= 2[50-(1/2)Q]
2P = 100 – Q
2P = 100 – Q
Слайд 18The Mathematics of Demand Functions
A Second Example
2P = 100 – Q
Q
+ 2P = 100 – Q + Q
Q + 2P = 100
Q + 2P = 100
Слайд 19The Mathematics of Demand Functions
A Second Example
Q + 2P = 100
– Q + Q
Q + 2P = 100
Q + 2P – 2P = 100 –2P
Q = 100 – 2P
Q + 2P = 100
Q + 2P – 2P = 100 –2P
Q = 100 – 2P
Слайд 21The Mathematics of Demand Functions
Some Assignments
P = 12 – 3Q
Q =
100 – 10P
Q = 4 – (1/3)P
P = 10 – 0.1Q
