2. The following data of a particular firm choosing a netput vector at
different prices was collected during the last financial period: at prices (1, 1),
the firm's netput vector is (-2,5). At prices (3,1), the firm's netput vector
is (-1,2). At prices (1,2), the firm's netput vector is (-4, 10).
a) Is this behaviour consistent with the profit-maximising model of the
firm?
b) Draw a precise graph of the largest possible production possibility set
Z based on this data. Briefly describe how you obtained it.
