Evaluating Functions: Introduction to Function Notation

This video tutorial teaches how to evaluate functions using function notation by substituting specific domain values. It explains the concept of a function as a relation where each X value corresponds to one Y value. The video demonstrates how to determine if a relation is a function using the vertical line test and provides examples of evaluating functions with different domain values. Common misunderstandings about function notation are addressed, emphasizing that F of X does not equal X. The tutorial concludes with a summary of the key points covered.
