For a linear homogeneous production function, multiplying all inputs by a constant factor α will result in the output increasing by the same factor. Hence, when α = 2, the output will increase by a factor of 2.
Thus the correct answer is (a).
Output (𝑄) | 1 | 2 | 3 |
Total Costs (𝑇𝐶) | 4 | 13 | 32 |
