To add to this statement...
Who goes through the difficulty of leading up to and teaching quadratics to students and then follows it up with an activity that has nothing but a circumstantial relationship to all that work?
Circumstantial = Curved line drawn on a piece of paper.
If this was an activity following a real treatment of quadratics then it would involve an algebraic analysis of the situation given. Period.
