How does one create a parabola?

A parabola can be created by plotting points that satisfy the quadratic equation of the form (y = ax^2 + bx + c), where (a), (b), and (c) are constants. Alternatively, it can be formed geometrically by taking a fixed point (the focus) and a fixed line (the directrix); the set of all points equidistant from both the focus and the directrix defines the parabola. To visualize it, you can also use graphing software or tools to draw it based on these principles.
