    The height to which a plant grows during the first six months is given by the following function: f(x)=36x-3x2 ; 0<=x<=6 where x is the age of the plant in months and f(x) the height in centimeters above the ground after x months.
    1. What height would the plant reach after 3 months? [Blank]
    2. At the end of how many months will the plant reach its maximum height [Blank]
    3. Hence calculate the maximum height to which the plant will grow [Blank]
