Assuming the parabola is of the form y = ax^2 + bx + c or y= a(x-h)^2 - k, you look to the 'a' coefficient to determine whether the parabola has undergone a vertical "stretch" or "shrink." If a>1, then it's a stretch. If 0<a<1, then it's a shrink.
If, by the way, the a is negative, this test still works... just ignore the negative sign. So if for example a = -2/3, it's a shrink, but if a = -3 it's a stretch. (Incidentally, the negative sign makes the parabola "reflect" over the x-axis.)

Parabola is the point at which the parabola is at its lowest or highest point?
A parabola is NOT a point, it is the whole curve.
Where is the line of symmety located on a parabola?
The line of symmetry located on a parabola is right down the center. A parabola is a U shape. Depending on the direction of the parabola it either has a x axis of symmetry or y axis of symmetry. You should have two equal sides of the parabola.
To find the value of a in a parabola opening up or down subtract the y-value of the parabola at the vertex from the y-value of the point on the parabola that is one unit to the of the vertex?
To find the value of a in a parabola opening up or down subtract the y-value of the parabola at the vertex from the y-value of the point on the parabola that is one unit to the right of the vertex.
How many foci does a parabola have?
A parabola has a single focus point. There is a line running perpendicular to the axis of symmetry of the parabola called the directrix. A line running from the focus to a point on the parabola is going to have the same distance as from the point on the parabola to the closest point of the directrix. In theory you could look at a parabola as being an ellipse with one focus at infinity, but that really doesn't help any. ■
What the the vertex of a parabola?
The vertex would be the point where both sides of the parabola meet.
What geometrical figure is umbrella?
Parabola
What is the formula for the volume of the parabola?
The formula is V = 0.A parabola is a 2-dimensional figure and therefore cannot have a volume.
What is the type of plane figure that is not closed?
A parabola or a hyperbola, for example.
Are all plane figures closed?
No, take a semicircle, it is a plane figure and is open. Or a parabola is also open and a plane figure.
What makes a parabola a parabola?
A parabola is a quadratic figure. It is an intersection of a right conical surface, a plane parallel to a generating straight line of the surface. Basically, it's an arc shape. It can open up, down, left, or right.
What is a parabola and ellipse?
A : A circle is a closed figure with eccentricity 1. Similarly, ellipse is also a closed fig with eccentricity less than 1 and parabola with greater than 1.
Can your bladder be stretched?
yes and no. sometimes you feel as if your bladder cannot hold as much urine as usual, right? But it does not mean that your bladder has shrunk. It is simply a symptom that means you may be having bladder problems. consult a doctor if you feel as if it has "shrunk".
What does stretched figure look like?
a stretched figure looks like a puddle of water. because lets say that if you have play dough and it was a flat rectangle and then you stretch it it would totally change its normal shape By:MIHAI LACHE
The dress has shrank or shrunk?
The dress has shrunk.
How do you find the endpoints of a parabola when you have the function of the line?
A parabola has no endpoints: it extends to infinity.A parabola has no endpoints: it extends to infinity.A parabola has no endpoints: it extends to infinity.A parabola has no endpoints: it extends to infinity.
What is the correct past tense Have shrank or have shrunk?
The correct past tense is "have shrunk." "Shrunk" is the correct past participle form of the verb "shrink."
For his shrunk shank?
for his shrunk part of leg between the knee & ankle shrunk is past form of shrink
