What is the graph of a quadratic formula?
In general, quadratic equations have graphs that are parabolas. The quadratic formula tells us how to find the roots of a quadratic equations. If those roots are real, they are the x intercepts of the parabola.

What is the x coordinate of the vertex parabola defined by the following function 3x plus x plus 7x plus 4?
The given equation is not that of a parabola.
Which graph could be used to find the solution of the system of equations y equals 2x plus 6 and y equals x2 plus 4x plus 3?
One way would be to graph the two equations: the parabola y = x² + 4x + 3, and the straight line y = 2x + 6. The two points where the straight line intersects the parabola are the solutions. The 2 solution points are (1,8) and (-3,0)
The maximum or minimum of a parabola depending on whether the parabola opens up or down?
A parabola opening up has a minimum, while a parabola opening down has a maximum.
Where the given equations are not linear?
Equations are not linear when they are quadratic equations which are graphed in the form of a parabola
How did Rene Descartes use the parabola?
Descartes used the parabola to illustrate algebraic equations. He put these equations on a visible plane using the Cartesian coordinate system and they sometimes took the shape of a "u" curve, or a parabola.
In quadratic equations what determines the width of the parabola?
the first number out in front you pig

What are quadratic equations used for?
quadratics are used for things like satellite dishes... there are more uses but that's only a basic one =) we are doing a project in math that requires quadratic equations. we make a parabola and put aluminum (or any other reflector) inside the parabola. we make a stick to put in the middle of the parabola to make a focus. we put the marshmellow on the focus and put the parabola in the sunlight. If done right then the marshmellow should heat up! cool huh?
The vertex of the parabola below is at the point -2 1 Which of the equations below could be this parabolas equation?

What is the focus of a parabola?
The focus of a parabola is a fixed point that lies on the axis of the parabola "p" units from the vertex. It can be found by the parabola equations in standard form: (x-h)^2=4p(y-k) or (y-k)^2=4p(x-h) depending on the shape of the parabola. The vertex is defined by (h,k). Solve for p and count that many units from the vertex in the direction away from the directrix. (your focus should be inside the curve of your parabola)
What type of equation results in a graph of a parabola?
A parabola looks like a frowning face :( or a smiling face :) The type of equation that would give you a parabola is called a Quadratic equation. Quadratic equations have x^2 as the highest exponent in the equation. ex: x squared + 2x + 1
The vertex of the parabola below is at the point 4 1 Which of the equations below could be this parabolas equation?
you didn't put any equations, but the answer probably begins with y= (x-4)^2+1
