Domain of Rational Functions

The video tutorial explains how to find the domain of rational functions by identifying discontinuities, which are values that make the denominator zero. It provides examples of single and multiple discontinuities and discusses removable discontinuities, emphasizing the importance of setting the denominator equal to zero to find undefined values.

What is the main focus when finding the domain of rational functions?

Explain why we cannot divide by zero when dealing with rational functions.

In what scenarios would the numerator affect the domain of a rational function?

What does it mean when we say a function is continuous in the context of rational functions?

What steps should be taken to find the values that make the denominator equal to zero?

How do you represent the domain in interval notation when there is a discontinuity?

Describe the process of finding the domain when given a product of two expressions.

What is the significance of the numerator when determining the domain of a rational function?

What is a removable discontinuity and how does it differ from other types of discontinuities?

How do you identify the values that are undefined for a function based on its graph?
