    Graphing Ti-84
Click For Summary
SUMMARY

The discussion centers on troubleshooting graphing issues with the TI-84+ calculator, specifically regarding incorrect slope and positioning of the graph. Users have identified that resetting the RAM does not resolve the issue, suggesting that the problem may relate to screen resolution settings affecting the visual output. To verify the slope, it is recommended to use the CALCULATE > dy/dx function and to trace points to ensure that the (x, y) values are accurate. The importance of confirming the nature of the function being graphed is also highlighted.

PREREQUISITES
  • Understanding of TI-84+ graphing calculator functions
  • Familiarity with graphing equations and slope concepts
  • Knowledge of using the CALCULATE feature on TI-84+
  • Basic understanding of function types (linear vs. non-linear)
NEXT STEPS
  • Explore TI-84+ graphing window settings for optimal resolution
  • Learn how to effectively use the CALCULATE > dy/dx function on TI-84+
  • Research methods for verifying function types and their characteristics
  • Investigate common troubleshooting techniques for TI-84+ graphing issues
USEFUL FOR

Students, educators, and anyone using the TI-84+ for graphing equations who seeks to troubleshoot and optimize their graphing experience.

I'll put in an equation using the y= function, that I've found out on my own, and I know to be correct, yet when I hit graph, lately the slope will be wrong, and the line will be in the wrong place, I've even reset the ram, to no effect. When I go into the table none of the original points I used for this equation are in it. Why would this be a correct solution??

When you say "the slope will be wrong," you mean the the visual output? If this is so, then it has to do with the screen resolution. You may be able to fix this in the settings for the graphing window. However, you may not be able to see the entirity of the domain or range when you do this. To make certain the slope is correct, you can always use CALCULATE > dy/dx. Or, you can trace the points and make certain that the (x, y) values match.

What is the function? Is it really a line?
