How to Change WINDOW Settings on a TI-84 Calculator

Introduction

Many graphing problems are really window problems. If the graph looks blank, flat, or cut off, the calculator may be drawing correctly but showing the wrong part of the plane.

You can practice this workflow with the online TI-84 calculator on this site, then repeat the same steps on a physical calculator in class or during homework.

Step-by-step workflow

1. Press WINDOW to view the current graph range.
2. Set Xmin and Xmax to cover the x-values you need.
3. Set Ymin and Ymax to include expected outputs.
4. Keep Xscl and Yscl readable.
5. Press GRAPH again and adjust if important points are hidden.

Practice example

For `Y = X^2 - 50`, try Xmin `-10`, Xmax `10`, Ymin `-60`, and Ymax `60` to see more useful detail.

Tips for better results

• Clear old entries before starting a new problem.
• Use parentheses when the expression has fractions, roots, or grouped terms.
• Compare the calculator result with the original question so you know what the number means.

Common mistakes

• Assuming a blank graph means the function was entered incorrectly.
• Setting Xmin larger than Xmax.
• Using a y-range too small for a steep function.

FAQ

Can I practice this on the online calculator?

Yes. Use the calculator on this site for practice and review, especially when you want to repeat a workflow several times.

Is the workflow exactly the same on every TI-84 model?

Most core steps are similar across TI-84 and TI-84 Plus models, but menu names and screen details can vary slightly.
