Dividing two functions and finding the constraint

The video tutorial covers the basics of division in functions, focusing on rational functions and their simplification limits. It explains why certain operations, like taking the square root of a negative number, result in imaginary numbers. The tutorial also addresses the concept of division by zero, explaining why it is undefined and how to set constraints to avoid it. The key takeaway is understanding the importance of constraints in division to prevent undefined operations.

How do you determine the values that cannot be included in the domain of a rational function?
