Question: annotation option with transformed plot

Hello, I am trying to use the annotation plot option to display coordinates in a function such as the example below that I created and successfully executed in Maple Flow::

However, when I apply this to another function that I have created, I cannot get the coordinate annotations to display. It appears to me that the syntax is correct and matches my example above, but there is something not correct and I am not seeing the problem. If anybody has any suggestions, I would appreciate any help.
