The range of a function is the set of all real values of y that you can get by plugging real numbers into x.

The domain of a quadratic function is always. If the vertex is a maximum the range is all real numbers less than or equal to the y value. The graph of this function is shown below. The domain of any quadratic function in the above form is all real values.

The domain of a quadratic function in standard form is always all real numbers meaning you can substitute any real number for x. If the vertex is a minimum the range is all real numbers greater than or equal to the y value. Therefore the domain of the quadratic function in the form y ax 2 bx c is all real values.

The domain of a quadratic function consists entirely of real numbers. The domain of a function is the set of all real values of x that will give real values for y. Domain of a quadratic 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.
