Question about Texas Instruments TI-84 Plus Calculator
Try taking the batteries out for more than 30 seconds, then holding on while putting them back in. Then press enter when you try to graph.
If that doesn't work, there seems to be a problem with your firmware, you will want to send the calculator back to TI.
Best of luck!!!
