Easier to show you a simple example as I forget the formulaic approach.
X2 + 4X - 6 = 0
add 6 to each side
x2 + 4X = 6
Now, halve the linear term ( 4 ), square it and add it to both sides
X2 + 4X + 4 = 6 + 4
gather the terms on the right side and factor the left side
(X + 2)2 = 10
subtract 10 from each side
(X + 2)2 - 10 = 0
(- 2, - 10 )

Do you have find the croodinates for the vertex for the quadratic function?
Yes, the coordinates for the vertex of a quadratic function in the form (y = ax^2 + bx + c) can be found using the formula (x = -\frac{b}{2a}) to determine the x-coordinate. Once you have the x-coordinate, substitute it back into the original equation to find the corresponding y-coordinate. This gives you the vertex in the form ((x, y)).
How do you look at a graph and tell what the quadratic function i?
To determine the quadratic function from a graph, first identify the shape of the parabola, which can open upwards or downwards. Look for key features such as the vertex, x-intercepts (roots), and y-intercept. The standard form of a quadratic function is ( f(x) = ax^2 + bx + c ), where ( a ) indicates the direction of the opening. By using the vertex and intercepts, you can derive the coefficients to write the specific equation of the quadratic function.
What is a technique used to rewrite a quadratic function in standard form to vertex from?
A common technique to rewrite a quadratic function in standard form ( ax^2 + bx + c ) to vertex form ( a(x - h)^2 + k ) is called "completing the square." This involves taking the coefficient of the ( x ) term, dividing it by 2, squaring it, and then adding and subtracting this value inside the function. By rearranging, you can express the quadratic as a perfect square trinomial plus a constant, which directly gives you the vertex coordinates ( (h, k) ).

What different information do you get from vertex form and quadratic equation in standard form?
The graph of a quadratic function is always a parabola. If you put the equation (or function) into vertex form, you can read off the coordinates of the vertex, and you know the shape and orientation (up/down) of the parabola.
What things are significant about the vertex of a quadratic function?
It is a turning point. It lies on the axis of symmetry.
What is the maximum and minimum of quadratic function parent function?
The minimum is the vertex which in this case is 0,0 or the origin. There isn't a maximum.....
What name is given to the turning point also known as the maximum or minimum of the graph of a quadratic function?
vertex
How would you use intercepts to find the vertex in a quadratic equation with two x intercepts?
The vertex must be half way between the two x intercepts
In the vertex form of a quadratic function y equals a the quantity of x-b squared plus c what does the b tell you about the graph?
The standard form of the quadratic function in (x - b)2 + c, has a vertex of (b, c). Thus, b is the units shifted to the right of the y-axis, and c is the units shifted above the x-axis.
What is the maximum or minimum of a quadratic equation called?
The vertex.
How can you use a graph to find zeros of a quadratic function?
The zeros of a quadratic function, if they exist, are the values of the variable at which the graph crosses the horizontal axis.
