what situation an increase in the price of a input, will not increase the price of the firms cost curve

1. Explain for what situation an increase in the price of a input, will not increase the price of the firms cost curve.

2. A firms total cost curve is TCQ=10Q−5Q2+Q3, and its marginal cost curve is MCQ=10−10Q+3Q2. Over what range of output does the production function exhibit economies of scale, and ober what range does it exhibit diseconomies of scale?

3. A firm has the production function Q=min{2L,K}, find the cost function in the long run if wage is $2 and capital rental is $3.

4. A firm has the production function Q=L+2K, and that wage is $2 and capital rental is $3. and that capital is fixed at .

1. 1. find the cost function in the short run
   2. Find the average cost function in the short run
