Question: what is the difference between a polynomial and rational?
Answer: A polynomial of degree n has at most n real zeros and n−1 turning points. The degree of a polynomial function determines the end behavior of its graph. ... A rational function is a function of the form f(x)=P(x)Q(x), f ( x ) = P ( x ) Q ( x ) , where P(x) and Q(x) are both polynomials.
