    Thank you alot for this helpful Video!..but there is an example that says what is the Range of ✓x^2 -6x + 8
    I would be glad if you could give me any idea about it..thanks again...

      In the video, I talk about graphing your function to see the range. Is the squareroot over the entire polynomial? Try graphing it and then checking the limitations for the range.
      If you are looking to do it algebraically, find the inverse of the function and then identify the domain (that will be the original functions range). Keep in mind that radicals need to be positive numbers underneath the radical!
      I hope that helps! :)

    How do we solve for the range without using the graph and just using equations?

      You would need to find the inverse of the function, and then find the domain. Here's a page with more information on doing it algebraically: www.varsitytutors.com/hotmath/hotmath_help/topics/domain-and-range-of-rational-functions
