How to find the equation of an inverted parabola whose two points are given on the cartesian co-ordinate and the equation of its latus rectum??

Question

anonymous · Answer

Locate where the 2 points of the parabola is located

anonymous · Answer

I think

anonymous · Answer

then see if if is a vertical or a horizontal oriented parabola

anonymous · Answer

how? I think if the 2 coordinates of the 2 points on the parabola are given, then you can trace it visually what the orientation of the parabola is.

anonymous · Answer

knowing the orientation, use the appropriate formula.

anonymous · Answer

dude this parabola is inverted so it makes theta angle with the axes.. we have to find the equation

anonymous · Answer

an inverted parabola is just a parabola opening downwards or (leftwards haha) i think

anonymous · Answer

if downwards, then x^2 = -4py
if leftwards, then y^2 = -4px

anonymous · Answer

that's how i remember my parabola

anonymous · Answer

no!! it opens like this|dw:1357849602531:dw|
