If the first line of the display show Graph Func : Y= you should be able to draw your function.

If it says anything else, press F3 TYPE to select the graph type and select functional by pressing F1 key Y=.

After the graph type is set to Y=, type the second member of your function y= f(x) on the first line. Make sure the = sign after Y1= remains highlighted after you move cursor. Otherwise select the function by pressing F1:SEL. Press F6 Draw.

Be careful with trigonometric functions. If angle unit is radian, set window Zoom to standard. If angle unit is degree, you must open the Window utility and set Xmin=-190, Xmax = 190 to see at least a period.
