Function?
Function?
A relation where every input has exactly one output. No input can have multiple outputs.
Function test: Table
Function test: Table
Examine the table to see if any input (X) values are linked to multiple output (Y) values. If so, it's not a function.
Function test: Mapping Diagram
Function test: Mapping Diagram
Check if any input (arrow source) has more than one output (arrow destination). If so, it's not a function.

Study Notes
Graph representing a function
- The graph does not represent a function because the vertical line test shows repeating input values
Relation as a function
- The relation is not a function because the x-value 11 has two y-values paired with it.
