Math Problem Statement
The temperature in a greenhouse, recorded over a period of 10 minutes, is represented by the equation: T = 0.5(t + 3)(t + 4)(5 – t) where t is time in minutes and T is temperature in degree Celsius Sketch the curve. Find the domain and range of T. After how many minutes is the temperature first below 40 °C? Use your graph to work out an approximate answer. At 50 °C, plants suffer from thermal death. Do you think this greenhouse is an effective one? Give reasons for your answer
