It can be either depending on its minimum value or its maximum value
When the coefficient of the y term ( a ) in the equation of a parabola is negative, the parabola opens downward. This means that its vertex is the highest point on the graph. Conversely, if ( a ) were positive, the parabola would 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.
A parabola opens downward when the coefficient of its ( x^2 ) term (denoted as ( a )) is negative. This means that the vertex of the parabola is the highest point on the graph. Conversely, if ( a ) is positive, the parabola opens upward.

If a is greater than zero then the parabola opens upward.
Opens downward.
X2 + whatever would open upward. - X2 + whatever would open downward. y2 + whatever would open to the right. - y2 + whatever would open to the left.
open upward
A parabola opens upward when its leading coefficient (the coefficient of the (x^2) term in the quadratic equation (y = ax^2 + bx + c)) is positive. This means that as you move away from the vertex of the parabola in both the left and right directions, the values of (y) increase. Consequently, the vertex serves as the minimum point of the parabola.
A parabola solution on a graph appears as a symmetrical U-shaped curve. It can open either upward or downward, depending on the coefficient of the squared term in its equation (e.g., (y = ax^2 + bx + c)). The highest or lowest point of the parabola is called the vertex, and the axis of symmetry runs vertically through this point. The shape is defined by how wide or narrow it is, which is influenced by the value of (a).
Changing the value of a parabola's coefficient from positive to negative causes the parabola to open downward instead of upward. This transformation affects the vertex's position and the overall direction of the graph. As a result, the maximum point becomes the vertex, while the minimum point is no longer defined. The shape is inverted, leading to different intercepts and behavior in relation to the x-axis.
Their noses are both at the origin, and they both open upward, but y=4x2 is a much skinnier parabola.
