Ответ:
We are asked to write the equation of parabola with focus
and directrix
.
Let us say that point (x,y) is on parabola.
We know that any point on parabola is equidistant from focus and directrix. Using distance formula we will get:
Square both sides:
Therefore, our required equation would be
.
