To have better understanding on domain and range of a quadratic function let us look at the graph of the quadratic function y x 2 5x 6. Range of quadratic functions. This video tutorial provides a review on how to find the domain and range of a function using a graph and how to write or express it using interval notation.

Therefore in general the domain of any quadratic function is all real numbers. I highly recommend that you use a graphing calculator to have an accurate picture of the. 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.

Learn how you can find the range of any quadratic function from its vertex form. So the domain of the function is. Summary of domain and range of a parabola in tabular form.

Range of a quadratic function. This is the currently selected item. 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.

To find the range is a bit trickier than finding the domain. Range of a function. The range of a function is the set of output values when all x values in the domain are evaluated into the function commonly known as the y values this means i need to find the domain first in order to describe the range.
