Solution 34579: Blank Screen When Displaying a Graph on the TI-84 Plus C Silver Edition Graphing Calculator.
Why do I get a blank screen when I try to display a graph on my TI-84 Plus C Silver Edition graphing calculator?
If a blank screen is displayed when graphing a function, it may be that the Window settings on the calculator are not appropriate for the function being graphed.
The ZoomFit command allows the calculator to set the Window settings so that the function can be displayed properly.
To use the ZoomFit command:
• Enter the function in the Y= Editor.
• Press [ZOOM] and Scroll to 0:ZoomFit.
• Press [ENTER].
Please see the TI-84 Plus C Silver Edition guidebook for additional information.
