[Maxima] How to assign a derivative of a function to a new function?

I am trying to assign a derivative to a new function, in order to know
the value of the derivative of the function at one point.
In the example below, I first assign a third degree polynomial to y(x).
Then I assign the derivative of that function to another function (dy(x)).
When I check, dy(x) shows well the derivative of the function y(x).
When I want to know the value of dy(x) in x=0, I get an error message.
Does anyone have a solution to my problem?
Non-variable 2nd argument to diff:
-- an error. To debug this try debugmode(true);
