How do you know if the parabola is up or down?

If the x is squared, the parabola is vertical (opens up or down). If the y is squared, it is horizontal (opens left or right). If a is positive, the parabola opens up or to the right. If it is negative, it opens down or to the left.

Beside this, how do you know if a function opens up or down?

There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

Subsequently, question is, how do you move a parabola up and down? The function y=x2+b has a graph which simply looks like the standard parabola with the vertex shifted b units along the y-axis. Thus the vertex is located at (0,b). If b is positive, then the parabola moves upwards and, if b is negative, it moves downwards. Similarly, we can translate the parabola horizontally.

Also know, why does a parabola open down?

If x is big and negative, and a is positive, then ax2 will again be very big and positive. So if a is positive, the parabola opens upwards. If a is negative then if x is big (positive or negative) the opposite occurs, and ax2 will be very big and negative with the parabola opening downwards.

What is half a parabola called?
