Exploring Function Notation

The video tutorial covers the concept of function notation, starting with basic equations and moving to more complex examples. It explains how to determine if a graph represents a function using the vertical line test and how to solve equations for Y to check if Y is a function of X. The tutorial also addresses common misunderstandings about function notation and provides advanced examples, including a word problem that illustrates the practical application of function notation. The video concludes with a discussion on domain and range.
