2. (3 points) Let's continue to use the situations above for the following questions out only as -nd ..I. A. Tare the derivative of each of the short run production functions above to find the formula for marginal product. B. Ev-luate each of these marginal product functions when the variable input = 4 C. Assume that use P=2 and w=7. Plug these values, along .. ith the values from part B, into the relationship *MP =w. For each of these, is 4 units of the input too little, too much, or just right: Explain
