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.

What is the implied domain of a function and why is it important?

How do you determine the values of X that are not in the domain of a function?

Explain the significance of setting the denominator equal to zero when finding the domain.

What is interval notation and how is it used to express the domain of a function?

Describe how to graphically represent the domain of a function with excluded values.
