Defining the

Production Function

The formula can be read since " quantity of

quantity

result is a function of the inputs

listed inside the parentheses”

Q = f (L, T, M…)

where

Q sama dengan quantity of end result

L = quantity of labor input

E = volume of capital input

y

M = level of materials suggestions

Short-run production function:

involves by least one fixed type

Long term production function:

production procedure in which almost all

inputs are variable

Competition implies that little product

reduces, eventually getting

AP and MEGA-PIXEL: Short-run

Creation Function

Between zero and L2, MEGA-PIXEL curve

is placed above AP curve, leading to AP

contour to increase

Listed below L2, MEGA-PIXEL curve is below AP

curve, causing AP competition to

reduce

Therefore , MEGA-PIXEL curve must

intersect AP curve in maximum

point of AP curve
