Can you help with question 1?

EMS FOR SECTION 3.1
1. Show that
8(x, y) = x'+y' - 3x - 2y defined for x > 0, y > 0
is strictly convex, and find its (global) minimum value.
2. A firm produces two output goods, denoted by A and B. The cost per day is
C(x, y) 0.04x² -0.01xy +0.01y +4x +2y +500
when x units ofA and y units of B are produced (x > 0, y > 0). The firm sells all it produces
at prices 13 per unit of A and 8 per unit of B. Find the profit function r (x, y) and the values of
x and y that maximize profit.
SN 3. (a) Referring to Example 2, solve the problem max pv"v-91u1-92vz.
1/3 1/2
(b) Let n (p, q1, 92) denote the value function. Verify the equalities in (*) in Example 4 for
this case.
SECTION 3.2 / LOCAL EXTREME POINTS
111
of f that is neither a local maximum point nor a local minimum point is called a saddle
point of f. Thus, arbitrarily close to a saddle point, there are points with both higher and
lower values than the function value at the saddle point. Figure 1 illustrates these concepts
in the case of a function of two variables.
