Renaming a Relation

Each relation type has a default naming convention. For example, the default name for functions is fn(x). (The number represented by n increases as you create more functions.) You can replace the default name with a name of your choice.

Note: If you want to use a custom name as a convention, you must enter it manually for each function.

1. In the entry line, delete the existing name. For example, delete the "f1" from "f1(x)". You can use the right and left arrow keys to position the cursor.

2. Type the replacement name.

3. If you are defining a new relation, position the cursor after the = sign and type the expression.

4. Press Enter to graph the relation with its new name.
