Please help me with a clear solution

2) (a) A rm has production function f(k,) = [x/E + y\" for some parameter or > 0. For what value of I does the function f have constant returns to scale? Provide an argument to support your answer. (b) Another rm has cost function C(wk, mg, q) 2 10+ (mg + 2x/mkwg+wg)q3/2 if q > 0 and C(wk, mg, 0) = C Find the conditional input demand functions Mark, mg, q) and ick, mg, q). Draw the MC and AC functions 3) A rm has SC and LC functions graphed below. In a new gure plot the corresponding SMC, SAC, LM( and LAC functions. Be precise
