  • If your TI-84 will only graph one function at a time, go to  APPS, Transform, Uninstall.
  • If you are missing a list, such as L1 or L2, go to STAT, EDIT, 5:SetUpEditor.
  • If you would like to see the correlation coefficient (R value) for a regression, go to your catalog (2nd 0) and scroll down until you see DiagnosticsOn.  Select it, then push Enter.
  • If you get an Invalid Dim error or a Dim Mismatch error, either double check your data entry in your Stat Lists or turn your Plots off.
