In that case it opens upwards.
The equation that describes a parabola opening up or down with its vertex at the point ((h, v)) is given by (y = a(x - h)^2 + v), where (a) is a non-zero constant. If (a > 0), the parabola opens upwards, while if (a < 0), it opens downwards. The vertex form allows easy identification of the vertex and the direction of the parabola's opening.
It is an up parabola.
A parabola opening up has a minimum, while a parabola opening down has a maximum.
To find the value of a in a parabola opening up or down subtract the y-value of the parabola at the vertex from the y-value of the point on the parabola that is one unit to the right of the vertex.

No. A parabola can open up or down.
Vertex
If a is positive, then the parabola opens upwards; if negative, then it opens downwards.
Opening up, the vertex is a minimum.
when you have y=+/-x2 +whatever, the parabola opens up y=-(x2 +whatever), the parabola opens down x=+/-y2 +whatever, the parabola opens right x=-(y2 +whatever), the parabola opens left so, your answer is up
No, a parabola is the whole curve, not just a part of it.
