Explain Production function with one Variable with help of Diagram?

A production function with one variable illustrates the relationship between the quantity of one input (typically labor) and the output produced. It generally shows diminishing returns, where each additional unit of the input contributes less to output than the previous one after a certain point. In a diagram, the x-axis represents the quantity of labor, while the y-axis represents output. The curve typically rises at a decreasing rate, reflecting the principle of diminishing marginal returns.
