What are the zeros of a parabola?

They are the x-values (if any) of the points at which the y-value of the equation representing a parabola is 0. These are the points at which the parabola crosses the x-axis.


What are the roots of a parabola?

I think you are talking about the x-intercepts. You can find the zeros of the equation of the parabola y=ax2 +bx+c by setting y equal to 0 and finding the corresponding x values. These will be the "roots" of the parabola.


A parabola always has at least one and at most two zeros?

Nope. False.


How is the x-value of the vertex of a parabola related to the zeros of the function?

For a parabola in a normal position ... with its nose either straight up or straight down ... the x-value of the vertex is midway between the zeros of the function, i.e. their average.


Where a parabola crosses the x-axis?

These are called the zeros of the equation. They are the places where y=0


What are the zeros of functions and what do they represent?

The zeros of functions are the solutions of the functions when finding where a parabola intercepts the x-axis, hence the other names: roots and x-intercepts.


How do you find the endpoints of a parabola when you have the function of the line?

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 do you find the equation of a parabola if you know the equation of the tangent that touches it?

You need more than one tangent to find the equation of a parabola.


How do you draw a parabola on an equilateral triangle?

To graph a parabola you must find the axis of symmetry, determine the focal distance and write the focal as a point, and find the directrix. These are all the main points you need to be able to draw a parabola.


How do you find a parabola opening up or down?

If you can mash the equation for the parabola into the form Y = Ax2 + Bx + C, then the parabola opens up if 'A' is positive, and down if 'A' is negative.
