Annie remembers the Water Balloon Contest and wants to try her skill at launching a balloon. Her balloon’s flight can be modeled by the function   where is the horizontal distance (yd) the balloon has traveled from the goal line, and is the height (yd) of the balloon above the ground.  

  1. Sketch a graph of the function and label the x- and y-intercepts. What do the intercepts tell you about the flight of the balloon?

    The intercepts are places where the height equals .

  2. What is the maximum height the balloon reaches? Justify your answer.
