Combining Functions by Dividing

This lesson covers how to create a new function by dividing two functions. It explains finding zeros of a function through factoring and graphing, addresses common misunderstandings in simplification, and demonstrates dividing functions f(x) by g(x) and g(x) by f(x). The lesson highlights the importance of handling undefined points and defining the domain of the resulting function. Graphical representations are used to illustrate concepts, emphasizing the need to avoid division by zero.
