finding points on polynomials

hi suppose i have points on circle of the form c=<100x2 double> and i have four polynomials p1,p2,p3,p4, then how i can evaluates these polynomial on c and plot data separatly. thanks in advance.

How are the polynomial represented?

Are they polynomials or are they multinomials in two variables (corresponding to the two columns of c) ?
