Why is any parabola that opens upward or downward a function?
MaddieHughesgp2921
It is a function because for every point on the horizontal axis, the parabola identified one and only one point in the vertical direction.

The parabola opens downward the vertex is called?
The maximum.
If the parabola opens upward the vertex is called the?
maximum point :)
Which way does a parabola open when the coefficent of its x2-term a is negative?
Opens downward.
An equilateral triangle is inscribed in a parabola with its vertex at the vertex of the parabola how do you find the length of the equilateral triangle?
First you need more details about the parabola. Then - if the parabola opens upward - you can assume that the lowest point of the triangle is at the vertex; write an equation for each of the lines in the equilateral triangle. These lines will slope upwards (or downwards) at an angle of 60°; you must convert that to a slope (using the tangent function). Once you have the equation of the lines and the parabola, solve them simultaneously to check at what points they cross. Finally you can use the Pythagorean Theorem to calculate the length.
What is maximum or minimum of a parabola depending on whether the parabola opens up or down?
Vertex
A parabola that opens upward?
Is a parabola whose directrix is below its vertex.
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.
The parabola opens downward the vertex is called?
The maximum.
How do you know if a parabola opens up or down?
I think it's like this: x2+3x-5 So if the x2 part is a positive then it opens upward but if it's negative it goes downward.
If the parabola opens downward the vertex is called the?
The maximum point.
If the parabola opens upward the vertex is called?
maximum point :)
If the parabola opens upward the vertex is called the?

How do you tell if a quadratic function is minimum value or a maximum vale?
Standard notation for a quadratic function: y= ax2 + bx + c which forms a parabola, a is positive , minimum value (parabola opens upwards on an x-y graph) a is negative, maximum value (parabola opens downward) See related link.
What way does the parabola open if a is greater than 0?
If a is greater than zero then the parabola opens upward.
Which way does a parabola open when the coefficent of its x2-term a is negative?
Opens downward.
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)
When a parabola opens upward the y coordinate of the vertex is a what?
Opening up, the vertex is a minimum.
