For a manufacturing process, the dominant value of net present value is given by f₁ = 35x^0.5+22, and the dominant value of the global warming potential is f₂ = 5x² + 10x + 100. Here, x represents the energy use in the process. For this process, determine the Pareto curve. Determine the feasibility and optimality of designs with [GWP, NPV] values of [6000, 100], [260, 92], [12000, 300]. Justify your answers.
