researchers found that the relationship between the yield of crop and the amount of watering could be modeled by y = -1478 + 3345x - 446x^2, where y is the yield, in kilograms per hectare (kg/ha), and x is the annual amount of water, in hectare-metres (ha-m). how much water produces the greatest yield?
