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 can be said of an ellipse when the two denominator values in its standard equation are the same?
When the two denominator values in the eclipse standard equation are the same, it can be said to be in foci.
How do you find the x-intercept of a parabola?
Factorise equation, and look at what x values are needed for the equation to equal zero. Eg. x^2+5x+6 (x+3)(x+2)=0 So parabola intercepts x axis at -3 and -2.
How do you find the vertex of the parabola given by y equals -3x2 plus 12x-1?
-3x2+12x-1 = y Solve the quadratic equation when y = 0 by means of the quadratic equation formula which gives x values of 3.914854216 and 0.085145784. Add these values together and divide them by 2 which is 4/2 = 2 and this is the line symmetry of the parabola. Substitute 2 for x into the original equation to find the value of y: So the vertex is at (2, 11) Remember that the parabola has a maximum value because the coefficient of x2 is negative in other words it will face downwards.
What is the root of a parabola?
In analytical geometry, the roots of a parabola are the x-values (if any) for which y = 0.

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.
Where do you find the roots when looking at a parabola?
-- The roots of a quadratic equation are the values of 'x' that make y=0 . -- When you graph a quadratic equation, the graph is a parabola. -- The points on the parabola where y=0 are the points where it crosses the x-axis. -- If it doesn't cross the x-axis, then the roots are complex or pure imaginary, and you can't see them on a graph.
Why is the domain of a parabola all real numbers?
The domain of a parabola is always all real numbers because the domain represents the possible x values. The x values are shown on the horizontal axis or x axis. Because, in a parabola, the 2 sides of the parabola go infinitely in a positive or negative direction, there is always a y value for any x value that u plug in to the equation.
How do you find the equation of a parabola in standard form given 3 points?
I suggest that the simplest way is as follows:Assume the equation is of the form y = ax2 + bx + c.Substitute the coordinates of the three points to obtain three equations in a, b and c.Solve these three equations to find the values of a, b and c.

What is quadratic functions?
It is a quadratic equation that normally has two solutions

A graph is a pictorial representation of what?
Any type of graph is a pictorial representation of data values. A continuous line graph, such as a curve or a parabola, may represent a variable equation.
How do you make a horizontal parabola?
A quadratic cartesian equation (an equation with x and y values only) produces a vertical parabola. A pair of parametric equation (one with more variables than x and y) produces a horizontal parabola:e.g:x=at^2y=2atYou're values of x and y will be in terms of a and this means your x axis will go from 0 to a to 2a to 3a etc. and your y axis goes from ...-3a to -2a to -a to 0 to a to 2a to 3a etc.Your parabola will now be horizontal.For more info on this, look up Further Pure 1 AS Maths- topic 3 coordinate systems.
