THE DEMAND FUNCTION AND CURVE
The demand Function
Qdx = f (Px, I, Py, T, N, )Qdx = f (Px) ceteris paribus
where: Qdx = Quantity demand of x
Px = Price of xI = Average Income
Py = Price of y as a related goods
T = Preference (taste)
N = Size of the market
= Special influence
Hukum Permintaan ( The Law of Demand )
Semakin rendah harga barang/jasa, maka jumlah
permintaan terhadap barang/jasa tersebut semakinmeningkat.

The Supply Function and Curve
The Supply Function
Qds = f (Px, Pi, Tg, G, Pr, )
Qds = f (Px) ceteris paribus
Where: Qds = supply quantity of xPx = price of x
Pi = price of input
Tg = Technology
G = Government Policy (Tx & S)Pr = Price of related goods
= special influence
