Understanding Function Notation

The video tutorial introduces function notation, explaining how it represents the relationship between inputs and outputs in a function. It covers examples using investment values, ordered pairs, tables, and graphs to illustrate how to interpret and convert between different representations of functions. The tutorial emphasizes understanding the notation and its application in various contexts.

What does function notation help us understand about a relation?

• The relation between two outputs

• The output as a function of the input

• The relation between two inputs

• The input as a function of the output
