<h2><u>ANS</u></h2><h3>A rational function is any function which can be written as the ratio of two polynomial functions, where the polynomial in the denominator is not equal to zero. The domain of f(x)=P(x)Q(x) f ( x ) = P ( x ) Q ( x ) is the set of all points x for which the denominator Q(x) is not zero.</h3><h2><u>Th</u><u>ank</u><u>You</u>!!!</h2>
