ab: Summary: A parabola is an interesting curve. What makes it interesting at
the secondary school level is the fact that this curve is presented in
both its contexts: algebraic and geometric. Being one of Apolloniusâ€™
conic sections, the parabola is basically a geometric entity. It is,
however, typically known for its algebraic characteristics, in
particular as the expression of a quadratic function. How do these two
entities, the geometric and the algebraic, coincide with one another?
In this paper, the author tries to answer this question. The author
starts by discussing some definitions of curves, followed by an
examination of the relations between them.
