Many high school and college classes require graphing calculators to help you understand principles of graphing. A graphing calculator is a hand-held calculator that can solve equations and graph solutions. Many types of graphing calculators are on the market, including the TI-89, HP 48G and the Casio FX-9750G Plus. Although each graphing calculator has unique operations, the basic steps required to make a graph are the same.
Instructions:
1. Press the "y=editor" button on your graphing calculator. The "y=editor" button is usually a "y=" symbol located toward the top left of the calculator.
2. Type your equation into the first line of the calculator using the numeric keypad. Do not type in the "Y=" part of the equation; the calculator does that for you. For example, if you want to graph Y=X^2, just type x^2.
3. Press the "Graph" key on the calculator. The graph key is usually located on the top row of the calculator.
Tips & Warnings
If you don't see a graph on your screen, it could be that your window is too large or too small. Press the "window" button on your calculator and check that the settings make sense for your graph. For example, if you are graphing x^2, you should see a graph if the window is set to Xmin of 0 and an Xmax of 10. To change the window, press the arrow keys on the keyboard to move to the number you want to change and then type the new number. When you are finished resetting the window, press "Graph."
