In this lesson, we continue to learn about relations and functions, specifically focusing on using function notation and finding inputs and outputs. We practice with different functions and their rules, and also discuss the importance of domain and range. The lesson culminates in more advanced problems involving multiple functions and variables, preparing us for future precalculus and calculus concepts.
More help and practice with relations and functions.
