Where does the word parabola come from and why is used for quedratic functions?

I don't know why its used for quadratic functions, but it comes from Greek prefix
para "alongside, nearby, right up to," and -bola, from the verb ballein "to cast, to throw." Understandably, parallel and many of its derivatives start with the same root. The word parabola may thus mean "thrown parallel" in accordance with the definition.

What is the name of the point you use to define a parabola?
All of the points on a parabola define a parabola. However, the vertex is the point in which the y value is only used for one point on the parabola.
Is parabola used in basketball games?
It can be used in anything that requires an object to go up, then come down due to gravity. So yes, it can be used for basketball games
Why tunnel used parabola shape?
for strength
What is the name of the line that is used to define a parabola?
directrix
How did Rene Descartes use the parabola?
Descartes used the parabola to illustrate algebraic equations. He put these equations on a visible plane using the Cartesian coordinate system and they sometimes took the shape of a "u" curve, or a parabola.
What is the name of a point that you used to define a parabola?
it's called the focus
Is there another not as common name for a parabola?
The parabola is a type of conic section, . The problem is that this is not a descriptive as the if the word "parabola" is used. The reason is that it is not the only geometric shape that can be derived by slicing a cone with a plane. Use the link below to see a drawing and learn more.
What is the directrix of a parabola?
"From the geometric point of view, the given point is the focus of the parabola and the given line is its directrix. It can be shown that the line of symmetry of the parabola is the line perpendicular to the directrix through the focus. The vertex of the parabola is the point of the parabola that is closest to both the focus and directrix."-http://www.personal.kent.edu/~rmuhamma/Algorithms/MyAlgorithms/parabola.htm"A line perpendicular to the axis of symmetry used in the definition of a parabola. A parabola is defined as follows: For a given point, called the focus, and a given line not through the focus, called the directrix, a parabola is the locus, or set of points, such that the distance to the focus equals the distance to the directrix."-http://www.mathwords.com/d/directrix_parabola.htm
Why the parabola used in satellite dish?
Parallel rays, such as those from a very distance source, are focussed by a parabolic reflector so that they all meet at the focus of the parabola. This results in a stronger signal.
What are quadratic equations used for?
quadratics are used for things like satellite dishes... there are more uses but that's only a basic one =) we are doing a project in math that requires quadratic equations. we make a parabola and put aluminum (or any other reflector) inside the parabola. we make a stick to put in the middle of the parabola to make a focus. we put the marshmellow on the focus and put the parabola in the sunlight. If done right then the marshmellow should heat up! cool huh?
How is parabola used in basketball?
A thrown basketball follows a path that can be approximated by a parabola. The approximation ignores air resistance and any curve imparted by spin on the ball. Over the distances involved, both are likely to be negligible.
What is practical use of parabola?
When you spin a parabola around its axis to make a curved surface, you get the surface with the shape that's used for the reflector in car headlights, flashlights, solar cookers, telescope mirrors, and satellite dishes.
