Evaluate the limit at infinity with square root

The video tutorial explains how to evaluate limits of a function as X approaches both positive and negative infinity. It demonstrates the process using a specific function, showing that the limit as X approaches infinity is -2/3, while the limit as X approaches negative infinity is 2/3. The tutorial concludes by encouraging students to verify the results using a calculator.

What is the significance of the result -2/3 in the context of this limit evaluation?

How does the absolute value affect the limit as X approaches negative Infinity?
