Production technology (function) of a firm determines whether a given level of output plan is feasible. Moreover, a production plan is said to be efficient if the firm produces at the maximum possible level its production technology permits. Suppose that a tech firm plans to produce 300 computers in each period. The firm employs 10 workers (x1) and 15 machinery (x2). Use the following production function and state whether this periodic plan is feasible and efficient. a) f(x₁, x₂) = x₁x₂ + 2x₂ + 120 b) f(x₁, x₂) = X₁X₂ + 2x₁ + 100 c) f(x₁, x₂) = 10min (3x₁, 2x₂) f(x₁, x₂) = 12min (6x₁, 4x₂) f(x₁,x₂) = 10x₁x₂ d) e) 1/2
