Domain Of Quadratic Equation

Its graph is called a parabola.

Domain of quadratic equation. A quadratic equation forms a parabola which has only a lowest or highest points. Let s first examine graphs of quadratic functions and learn how to determine the domain and range of a quadratic function from the graph. This is a quadratic function thus the graph will be parabolic.

If it s negative the function opens down. The range is all the possible values of y. All polynomial functions such as a second degree polynomial have domain of all reals.

Domain is legal x range is all y. The domain of this function is the set of all possible values of x which you can put in the equation and get a value for y. Domain of a quadratic function.

Therefore the domain of the quadratic function in the form y ax 2 bx c is all real values. Domain x values output domain and range of quadratic functions substituting any real value of x into a quadratic equation results in a real number. The domain of any quadratic function in the above form is all real values.

The general form a quadratic function is y ax 2 bx c. Because in the above quadratic function y is defined for all real values of x. F x 2x 2 3x 4.

I know that this will also have either a minimum or a maximum. So let s look at finding the domain and range algebraically. Our goals here are to determine which way the function opens and find the y coordinate of the vertex.
