positive.
If a is greater than zero then the parabola opens upward.
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.
When you look at the parabola if it opens downwards then the parabola has a maximum value (because it is the highest point on the graph) if it opens upward then the parabola has a minimum value (because it's the lowest possible point on the graph)
A parabola can open left, down, right, or left on a graph, if that's what you mean:\
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
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.
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.
maximum point :)
