# Writing a quadratic function in intercept form

I would like to know how to find the equation of a quadratic function from its graph, including when it does not cut the x-axis. The ordered pairs in the table correspond to points on the graph. Find an equation for the path of the ball. Does the shooter make the basket? Stop motioned picture of a boy throwing a basketball into a hoop to show the parabolic curve it makes.

Given a quadratic function in general form, find the vertex of the parabola. Rewrite the quadratic in standard form vertex form. Finding the Domain and Range of a Quadratic Function Any number can be the input value of a quadratic function.

Therefore, the domain of any quadratic function is all real numbers. Because parabolas have a maximum or a minimum point, the range is restricted. Since the vertex of a parabola will be either a maximum or a minimum, the range will consist of all y-values greater than or equal to the y-coordinate at the turning point or less than or equal to the y-coordinate at the turning point, depending on whether the parabola opens up or down.

Domain and Range of a Quadratic Function The domain of any quadratic function is all real numbers. Given a quadratic function, find the domain and range. Identify the domain of any quadratic function as all real numbers. Determine whether a is positive or negative. Solution As with any quadratic function, the domain is all real numbers.

We need to determine the maximum value. We can begin by finding the x-value of the vertex. Answer The domain is all real numbers. Determining the Maximum and Minimum Values of Quadratic Functions The output of the quadratic function at the vertex is the maximum or minimum value of the function, depending on the orientation of the parabola.

Minimum and maximum of two quadratic functions. There are many real-world scenarios that involve finding the maximum or minimum value of a quadratic function, such as applications involving area and revenue.

Finding the Maximum Value of a Quadratic Function A backyard farmer wants to enclose a rectangular space for a new garden within her fenced backyard. She has purchased 80 feet of wire fencing to enclose three sides, and she will use a section of the backyard fence as the fourth side.

What dimensions should she make her garden to maximize the enclosed area? Diagram of the garden and the backyard.

## Standard Form

The quadratic has a negative leading coefficient, so the graph will open downward, and the vertex will be the maximum value for the area.Algebra 2 Credit Recovery. Search this site. DOCUMENTS. Home. Unit 1: Functions. A. I can write a quadratic function in standard form given vertex or intercepts form.

B. I can write a quadratic function in intercept form given standard form.

 How to find the equation of a quadratic function from its graph Parabolas have two equation forms — standard and vertex. With just two of the parabola's points, its vertex and one other, you can find a parabolic equation's vertex and standard forms and write the parabola algebraically.
