Is this what a parabola is? i am too retarded to understand what the dictionary definition means

>symmetrical open plane curb
>formed by the intersection of a cone with a plane parallel to its side

wtf is this?

Imagine a regular cone, a tip at one end, circle
at another. Now take a slicer or flat piece of paper
and cut the cone from any part of the circle side
as long as the cut is with respect to the cone's
slope. That's your parabola.

Another definition: The curve formed between
the focus (a dot) and a directrix (a straight line)
such that the distance between directrix and
curve PLUS the distance between curve and
focus is always a constant.

ax^2 + bx + c is a parabola which is a 2nd degree polynomial.

My mistake, instead of PLUS it should be
EQUALS, and there's no "constant" to speak of.
That previous definition is for the ellipse.

Remind me again why 2nd order polynomials follow conic sections?

Because the double cone is a second order polynomial

If you expand any conic section equation and
group them in similar terms, term by term they
share characteristics from the general conic
section equation in pic related.

Also, Isaac Newton in his Principia Mathematica
have proven in a complex way that any conic
can be formed up to five random points on a
graph (provided three points aren't collinear),
which results in a degree 2 equation.

She obviously applied a floor function to that parabola OP.

With shit like this you just have to break it down into parts.
This isn't english, you have to treat it like listening to a retard speak, sometimes the beginning of the sentence is at the end or in the middle.

So start with what's a curb?
A curb is a curve, because you're retarded and made a typo.
Next, what does a curve look like when it's symmetrical? There you go, you already figured it out. The rest is some retarded definitionist's wet dream.

A parabola is defined by a line called a directrix and a point called a focus, and is said to be the set of all other points where d(point,focus)=d(point,directrix)
