WebOct 6, 2024 · Key Concepts. A parabola is the set of all points (x,y) in a plane that are the same distance from a fixed line, called the directrix, and a fixed point (the focus) not on the directrix. The standard form of a parabola with vertex (0,0) and the x -axis as its axis of symmetry can be used to graph the parabola. 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: \[(x-h)^{2}=4 p(y-k) \] A parabola is defined as the …
WebThe distance of the x coordinate of the point on the parabola to the focus is (x - a). The distance of the y coordinate of the point on the parabola to the focus is (y - b). Remember the pythagorean theorem. a^2 + b^2 = c^2. We know the a^2 and the b^2. We put them together and we get c^2 = (x - a)^2 + (y - b)^2.
