Parabola? What line? Which line, where? Lines do not have width.

You can move the parabola either right
or left by writing equation as:

-------------------
Notice that when

The vertex is at (a,0)
------------------
This is how you move the vertex from
(0,0) to anywhere on the x-axis
-----------------------------
Then, in order to move up or down,
you need:

----------------------
To make the parabola narrower ( skinny ),

where
To make the parabola wider ( fatter ),

------------
Say

---------------
A 2nd parabola is:

Here are the plots:

The skinnier one is:

Hope this helps
