Here it is! You should open a new document and select the Graph application. Your entry line is ready for f1(x), so type it in. I have changed the window from the standard viewing window to get a little nicer view of your function. Can you tell?

Here is how to change the window:
1) either press Menu, Window, Window Settings, and then edit the x min and x max values, as well as the y min and y max values, or:
2) double click on the end values of one of the axes, and change the number...then tab to the next end value for you to change!
