For this case we have the following equation:
 h = 270t-4.9t2
 We observed that:
 1) The equation is quadratic
 2) The quadratic term of the equation is negative, therefore, the parabola opens downwards.
 3) The object is launched with initial height equal to zero.
 Answer:
 The relationship between the height of the object and the elapsed time is quadratic.
