know brass is an alloy of copper and zinc, used in flxed proportions. The production function is given by: f(x1; x2) = minfx1; 2x2g, where x1 isthe amount of copper it uses and x2 is the amount of zinc that it uses in production.(a) Illustrate a typical isoquant for this production function in the graph below.x2 4030 2010 0 10 20 30 40×1 (b) Does this production function exhibit increasing, decreasing, or constant returns to scale? .(c) If the flrm wanted to produce 10 efironteries, how much copper would it need? How much zinc would it need? .(d) If the flrm faces factor prices (1; 1), what is the cheapest way for it to produce 10 efironteries? How much will this cost?. (e) If the flrm faces factor prices (w1; w2), what is the cheapest cost toproduce 10 efironteries? . (f ) If the flrm faces factor prices (w1; w2), what will be the minimal costof producing y efironteries? .
