I am referring to the online app that the videos show being used. It is not in this video, but in some others they show a TI-84 image of a calculator on the screen . Since I lost my calculator, I would like to download the app onto my computer.
Jesica -You did not say the calculator you are using, but on a TI-83 or TI-84 (most common graphing calculator used by high school students) the graphing function is accomplished by simply hitting the "Y=" key and entering the equation. Then, simply hit the "GRAPH" key.The TI calculators also have extensive help and online manuals on the web ... just Google it.Hope that helps
