maximum point :)
It is a function because for every point on the horizontal axis, the parabola identified one and only one point in the vertical direction.
Since a parabola is an open infinite curve, the area inside it is infinite.
A parabola is a two dimensional open curve. Its area is therefore infinite.
No. A parabola can open up or down.
positive.
If a is greater than zero then the parabola opens upward.
open upward
If the number in front of the x squared is negative, then the parabola will open upwards. The opposite occurs when the number is positive.
It can be either depending on its minimum value or its maximum value
Is a parabola whose directrix is below its vertex.

If the value of the variable is negative then the parabola opens downwards and when the value of variable is positive the parabola opens upward.
Their noses are both at the origin, and they both open upward, but y=4x2 is a much skinnier parabola.
