Answer:
True
Step-by-step explanation:
When we graph a production function, we obtain an upward-sloping curve whose gradient (or slope) reaches a peak, and then, begans to flatten until it is fully flat.
This is because the law of diminishing returns states that there is a point when capital and labor are used optimally, and after that point, any additonal unit of capital or labor has a lower marginal productivity.
I will attach a graph of the production function that illustrates this point.
