Step-by-step explanation:
i think the answer is both.
a polynomial in one variable can be expressed p(x)= (a(n)x^n)+(a(n-1)x^n-1)...(a(2)x^2)+(a(1)x^1)+(a(0)x^0) where powers of x are whole numbers and coefficient of x must be a real number. so,
case 1 i.e., in p(x), n=1 which is a whole number and the coefficients of x are real numbers
case 2 i.e., in p(x), n=1 which is a whole number and the coefficients of y are real numbers
I hope my answer helped you and don't forget i might be wrong.
