Function Operations and Expressions

The video tutorial covers the four basic operations on functions: addition, subtraction, multiplication, and division. It provides step-by-step examples of evaluating these operations with specific values and variables. The tutorial also discusses domain considerations, emphasizing the importance of avoiding undefined domains, particularly when dealing with fractions and radicals.
