In this tutorial, we'll be looking at how to enter an equation into graph mode and how to change the axes to display the graph as you would like it. Each time you open graph mode, the same settings will appear for the new graph that had been entered for the previous one, so your first attempt may not look right at all. To follow this video, reset your calculator first.
Choose graph mode 5 and then go to type and choose Y equals. Type the rest of the equation into Y1. Use the X Theta T key X. The X label for F5 is not the X that you need in your equation. Press execute.
Draw will give you the graph. In this demonstration, the minimum point is missing from the graph on the screen and the simplest way to change how the graph looks is to use the cursor keys to pan in any direction. Panning down, we'll get the vertex in to view. Plus will zoom in, keeping the middle point on the screen fixed and minus will do the opposite. You may not get the graph you want with these tools. There is a zoom menu which may be more useful to you. Selecting zoom brings up a menu with many options but we'll choose in. It works like plus, but you can choose the centre of the zoom by moving the cursor. And then execute. And now you can choose to zoom out and we're going to move the cursor once more to be the centre of the zoom. And execute.
