Problem 5. Write down all the first-order and second-order partial derivatives
for the Cobb-Douglas function
f(x, y) = ®
Ax y

Explain what is meant by saying that the function is homogeneous of degree
a +B and comment on the relationship between this property and the notion
of 'returns to scale: For the particular Cobb-Douglas function with A = 1,
a = 2, B = c with c > 0. Find the
gradient at the point (3, 2) of the contour which passes through that point.
