WebA parabola is the set of all points whose distance from a fixed point, called the focus, is equal to the distance from a fixed line, called the directrix. The point halfway between the focus and the directrix is called the vertex of the parabola. A graph of a typical parabola appears in Figure 3. WebOct 6, 2024 · The equation of the parabola is often given in a number of different forms. One of the simplest of these forms is: (x − h)2 = 4p(y − k) A parabola is defined as the locus (or collection) of points equidistant from …
