18 Getting Started
To graph a function, you must:
1. Display the Y= Editor.
2. Enter the function.
3. Display the graph.
Note: If you previously changed graph type in the mode settings, you
must change the type back to Func (the default setting) before you
graph.
Example: Graph the function Y = X2 + 1.
Note: If Y1 is not empty, press ‘. If there are additional entries in
the Y= Editor, press †‘ until all are clear.
Changing mode settings
The mode settings determine how entries are interpreted and how
answers are displayed on the TI-84 Plus.
