Question: dimension of the image

EDIT:
Let f:X->f(X)  be a polynomial function from C^n to C^p. Let r(X) be the rank of the Jacobian matrix of f in X. What is the maximal value of r(X) when X goes throught C^n ?

In other words, I'd want to obtain the maximal dimension of the components of im(f). 

How to proceed ?

Thanks in advance.
