I do it by drawing the axes, helping myself with the grid (there is an 
option on the ribbon to show or hide the grid).

define the function as a lambda expression :-)

($graph2d -3 3 100 (lambda (x) (expt x 2)))

I agree that it is more difficult than it should be. There is the thread

had forgotten about and shows some ways of using infix notation; it may 
be that it needs some work yet.
