If you do this you will interpolate the function x^2 on a P1 function space. 
But, you can do it.

        femfunction f(M:P2)=x^2;
will do what you want. Note that available keywords are P0, P1(default) and 
P2. If the mesh M is a mesh of hexahedra, this will build a Q2 function.

You can also solve problems with this kind of element :
        solve(u:P2) in ...
or compute integrals :

there are examples in the exercises from Sevilla that you can download from
