This is a quadratic grapher. When it tells you to input your A, B, and C terms, Please input them in the format Ax^2+bx+c. If you want to check this on your calculator, then windows settings are: X-Min: -240 X-Max: 240 X-Scale:1 Y-Min: -180 Y-Max: 180 Y-Scale:1 When you are done it will tell you your vertex, and you can press T to show the table. Press S to search through the table. When it is done searching, press S again when you are finished.
This graph can also do linear equations. Just put your A term as 0! THE VERTEX WILL NOT WORK FOR LINEAR EQUATIONS Hint=Sometimes the Search thing gets broken, just scroll down to 241 and you should find your 0. If your table bobs around -180 or 180 as a Y value, than it means that the Y vaule is > or < than what can fit inside this screen.
