A function such as (x^2*(x+1)^3)/((x-2)^2 * (x-4)^4) has a graph that is close to zero except for inf at x=2 & x=4, and a min at about x=2.47 of about 211. I don't understand how to march through the possible extremums in the way you suggested. By manually entering a tight range about potential extremums and using auto scale, I get a nice plot centered on my point of interest, and can then call for the extremum.
This seems particularly handy where an initial graph is flat so as to not suggest extremums exist or how many...
Clearly, I'm not understanding this (though my work around really shows the utility of the graphing capability interfacing with the home screen). I think this also speaks to a real need for a physical manual for a capable, complex tool such as the Prime...they were of such value for even recent offerings such as the 35s and the 15c LE! I can't imagine students, let alone their teachers taking as full advantage of this device without a physical manual...you can see all the questions appearing on this forum from folks that are highly experienced in this area...I wonder how perplexed a more general audience of folks that you hope to purchase this unit will be.
In any case, thanks for bringing this product into being, and I hope that HP will attach importance to this product offering/market.
