How would one solve the following question?

There is a price-taking rm that uses capital and labor to produce output. Since its capital is xed in the short run at some level I: , its short run pro- duction function is f0) = 411/4. The rm faces input prices w and r that are greater than zero. (a) What is the firm's short-run supply function :33? (b) What is the firm's short-run price elasticity of supply 533? The firm's long run production function is f(k, l) = all/ 4191/ 4 Where a > 0. (c) What is the firm's long-run supply function 533:? (d) What is the firm's long-run price elasticity of supply 5:51
