Define Function, Function Notation, Domain and Range

This video tutorial by Brian McLogan introduces precalculus students to functions, covering their characteristics, graph analysis, and the definition of a function. It explains the vertical line test, function notation, and the concepts of domain and range, providing a comprehensive overview of these foundational topics.

How do you find the minimum and maximum values of a function from its graph?

What are some examples of functions that do not pass the vertical line test?

What is function notation and how does it differ from traditional variable notation?

In what scenarios would a function not be defined?
