I am a new user of the CG10 Prizm which I bought for my son to use in high school. I ran across a graphing scenario which makes me think either the CG10 has a bug or the user doesn't know what he's doing (yet).
The equation is:
(x-4)^2(x+3)(x-2)^3
For some reason, the CG10 is not showing the line of the graph to go through the left most root (-3,0). I checked it on WolframAlpha, Desmos, and also a Ti-84+C emulator I have on my Android. All show the graph properly except for the CG10. Note: WolframAlpha image is skewed by the Y scale.
Have I missed something on the CG10? If I tell it to find the roots, it finds -3 just fine, but there is no line going through that point.
