7:Shade( from the DRAW menu. The instruction is
pasted to the home screen or to the program editor.
Shade( draws lowerfunc and upperfunc in terms of X on the current graph and shades the
area that is specifically above
lowerfunc and below upperfunc. Only the areas where
lowerfunc < upperfunc are shaded.
Xleft and Xright, if included, specify left and right boundaries for the shading. Xleft and
Xright must be numbers between Xmin and Xmax, which are the defaults.
