Draw isoquant curve for the following production functions.

Here Kdenotes quantity of capital input and Ldenotes the quantity of labor input.

In the graph, let Kbe on the vertical axis and Lbe on the horizontal axis.

(a) (,)==,F(K,L)=KL=Q,where

(1) =100,Q=100,

(2) =200,Q=200,

(3) =300.Q=300.

This production function is an example of Cobb-Douglas production technology.

(b) (,)=2+5=,F(K,L)=2K+5L=Q,where

(1) =100,Q=100,

(2) =200,Q=200,

(3) =300.Q=300.

This production function is an example of perfect substitutes production technology.

(c) (,)=min{2,5}=,F(K,L)=min{2K,5L}=Q,where

(1) =100,Q=100,

(2) =200,Q=200,

(3) =300.Q=300.

This production function is an example of perfect complements production technology.
