With all other factors held constant (such as light frequency, water temperature, air temperature, nutrient supply), the photosynthetic growth, I, in grams per day, for a certain plant, hydroponically grown in artificial light, depends on the light intensity, x, measured in kilowatts, according to the formula I(x) = 180x^2 - 90x^3 . What value of x (correct to two decimal places) maximizes the photosynthetic growth?
