Evaluate the right hand limit of a rational function with a radical

The video tutorial explains how to choose values larger than 9 and discusses the concept of limits as X approaches 9 from the right. It highlights the importance of understanding square roots and their approximations, emphasizing that the square root of a number slightly larger than 9 is not significantly larger than 3. The tutorial also covers the positivity of results when dealing with limits and stresses the importance of consistently using limit notation in mathematical work.
