I know how to work this problem, but how do I know that I use the equation y^2 = 4px instead of x^2 = 4py.

Please help this is so confusing!!!!

the parabola. I believe the word AN

implies that there is more than one possibility.

If there was only one possibility, the problem would have said: Find THE eguation of the parabola. So I believe an X or Y-parabola is correct.
