A firm produces its output using the following production function: f(x₁, x₂) = √√√x₁ - 1 + 4x2 where x₁ denotes the amount of factor 1 and x2 denotes the amount of factor 2. The market price of factor 1 is $4, and the market price of factor 2 is $10. (a) To produce y = 8 units of output with the lowest cost, how much factor 1 and factor 2 should the firm use? Find the optimal bundle of inputs and calculate the minimal cost.

Question

(b) Now, suppose the price of factor 2 has increased to $40, and the price of factor 1 is still $4. To produce ?=1 unit of output with the lowest cost, how much of factor 1 and factor 2 should the firm use? Find the optimal bundle of inputs and calculate the minimal cost.

A firm produces its output using the following production function:
f(x1, x₂) = √√√x₁ −1+ 4x₂
where x₁ denotes the amount of factor 1 and X2 denotes the amount of factor 2. The market price of factor 1 is $4, and the market
price of factor 2 is $10.
(a) To produce y =
8 units of output with the lowest cost, how much factor 1 and factor 2 should the firm use? Find the optimal
bundle of inputs and calculate the minimal cost.

Find the optimal bundle of inputs and calculate the minimal cost.
(c) Suppose the firm utilizes a new technology to produce output. According to the new production function, factors 1 and 2 must
be combined in fixed proportions. To produce 2 units of output, the firm needs to combine 3 units of factor 1 with a unit of factor
2.
If the price of factor 1 is $2 a unit and the price of factor 2 is $4 a unit, draw an isocost representing the lowest cost of producing 2
units of output.
