Parametric functions provide an easy mechanism for creating a graph that more accurately. reflects the physical position of a projectile. Similarly, it portrays circular functions as circles, rather than sine curves. Still, when looking at a static graph of a parametric function, the sense of movement is lost.
A parabola is a graph of a quadratic function, y = x2, for example. The line perpendicular to the directrix and passing through the focus (that is, the line that splits the parabola through the middle) is called the axis of symmetry. The point on the parabola that intersects the axis of symmetry is called the vertex, and is the point where the parabola is most sharply curved.
