Multiplying two functions to determine the domain

The video tutorial covers the multiplication of functions, emphasizing that unlike addition and subtraction, multiplication does not require common denominators. It explains the process of multiplying numerators and denominators separately. The tutorial then shifts focus to finding the domain of the resulting function, highlighting the importance of constraints. It discusses how certain values make the denominator zero, thus excluding them from the domain. The video concludes by explaining how to connect valid intervals using union notation.
