What Is The Domain Of A Quadratic Function

The graph of a quadratic function is a u shaped curve called a parabola.

In the quadratic function y x2 5x 6 we can plug any real value for x. Domain of a function. The range of a function is the set of all real values of y that you can get by plugging real numbers into x. Domain of a quadratic function.

Therefore the domain of the given quadratic function is all real values. Determine the domain and range of the function f of x is equal to 3x squared plus 6x minus 2. The domain of a function is the set of all real values of x that will give real values for y. Because in the above quadratic function y is defined for all real values of x.

In algebra a quadratic function a quadratic polynomial a polynomial of degree 2 or simply a quadratic is a polynomial function with one or more variables in which the highest degree term is of the second degree. Domain is all the x values or independent variable values that give us a real number answer. A quadratic polynomial with two real roots crossings of the x axis and hence no complex roots. If the vertex is a maximum the range is all real numbers less than or equal to the y value.

If the parabola opens up the vertex represents the lowest point on the graph or the minimum valueof the quadratic function. Therefore the domain of the quadratic function in the form y ax 2 bx c is all real values. To find the domain i need to identify particular values of x that can cause the function to misbehave and exclude them as valid inputs to the function. The domain of a quadratic function consists entirely of real numbers.

For quadratics the domain is all real numbers since there are no values that we would substitute in. The general form a quadratic function is y ax 2 bx c. Because y is defined for all real values of x. And i can take any real number square it multiply it by 3 then add 6 times that real number and then subtract 2 from it.

What is a set of all of the valid inputs or all of the valid x values for this function. The graph of this function is shown below. If the vertex is a minimum the range is all real numbers greater than or equal to the y value. So the domain of the function is.

The domain of a function is the set of all allowable values of the independent variable commonly known as the x values.
