1.
Explain the following
a. Production
b. Total Product
c. Marginal Product
d. Average Product
2. What is a production function?
3. Distinguish between linear and non – linear production functions. Outline the features of
the Cobb-Douglas production function.
4. Distinguish between production in the short run and in the long run.
5. State and explain the law of diminishing marginal returns and also outline the 3 stages of
production in the Short – Run for an expanding firm with reference to the table below.
With the aid of graphs (TP, MP, AP) using the completed data in the table, plot and show
the 3 stages.
