To determine

(a)

To find:

The geometric definition of a parabola.

Explanation

Approach:

A parabola is the set of points in the plane that are equidistant from a fixed point F (the focus) and a fixed line l (the directrix). The geometric representation of the parabola is shown below.

Here, F is the focus, l is the directrix
