What way does the parabola open if a is greater than 0?
If a is greater than zero then the parabola opens upward.
How does the value of a variable affect the direction the parabola opens?
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.
How does the graph of y 4x2 compare to the graph of y x2?
Their noses are both at the origin, and they both open upward, but y=4x2 is a much skinnier parabola.
How do you know if a parabola has a minimum or maximum value?
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)
In which direction does the parabola?
A parabola can open left, down, right, or left on a graph, if that's what you mean:\
What way does the parabola open if a is greater than 0?
If a is greater than zero then the parabola opens upward.
What does changing the value of a from a negative number to a positive number cause the parabola to do?
open upward
When the parabola concave downward and 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.
What would you want to be a parabola open upward or open downward?
It can be either depending on its minimum value or its maximum value
A parabola that opens upward?
Is a parabola whose directrix is below its vertex.
If the parabola opens upward the vertex is called?
maximum point :)
If the parabola opens upward the vertex is called the?
maximum point :)

The parabola for the function will point in which direction yx2 3x-4?
upward
The entire path of a projectile fired upward through the air can be represented as?
a parabola
