Notice the wording: Find AN equation of
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.
an engineer designs a satellite dish with a parabolic cross section. The dish is 15 ft wide at the opening and the focus is placed 4 ft from the vertex. find an equation of the parabola.
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!!!!
