Evaluating Function Notation and Its Applications

The video tutorial covers function notation, explaining how to use and interpret it. It begins with an introduction to function notation, followed by a discussion on independent and dependent variables. The tutorial then explains how to write function notation using ordered pairs and provides examples of evaluating functions. The video emphasizes the importance of understanding function notation and offers tips for creating shorthand notes.

What is the independent variable in a function?

• The domain or x value

• The output value

• The function notation

• The range or y value
