Learn to write the domain in interval notation of rational function

The video tutorial explains the concept of implied domain, focusing on identifying values that make the denominator zero, which are excluded from the domain. It transitions from set notation to interval notation, emphasizing the importance of understanding domain restrictions through graphical representation. The tutorial concludes with a detailed explanation of writing intervals using union symbols, preparing students for exams.
