I found it interesting that the first student did not realize that he had the equation of the parabola in part (1) itself, rather than re-doing it in part 2. Maybe he did realize it after the fact. However, it is difficult for me to put myself in the students' shoes. With math, most things are easy once you know them.

It looks like that the second student reached for the calculator too soon. Is this generally the case even with your better and more motivated students?
