Subtracting two functions reciprocal so we can find the domain

The video tutorial covers operations with functions, focusing on adding and subtracting them. It reviews subtracting rational expressions, similar to subtracting fractions, and emphasizes finding the least common denominator (LCD). The tutorial explains simplifying expressions using the distributive property and concludes with finding the domain of a function, highlighting the importance of identifying values that make the denominator zero.
