Hello, I'm having some problems getting functions to graph.
I am using a ti-83 plus. I am in function mode, and every other mode seems right as well. I go to y= and enter a basic polynomial function under y1 (such as y1 = 4x + 3). When I go to zoom, trace, or graph I get the error message "ERR:UNDEFINED".
My window settings are:
Xmin = 10
Xmax = 11
Xsc1 = 0
Ymin = 10
Ymax = 11
Ysc1 = 0
Xres = 1
I've consulted the manual but can't seem to figure anything out that relates to this problem. This is the same calculator I used in a statistics course, so perhaps one of the off-sets I changed for that course is interfering, although based on what I can tell I don't think that is the case.
This is also an urgent situation, so any help is very appreciated.
Edit: I posted this on another forum and got no replies. Please don't hesitate to post if you think you may know how to solve this problem. I'm not adept at this calculator by any means, so it could just be a very obvious mistake. Thanks.
