Definition and Domain of Rational Functions. A rational function is defined as the quotient of two polynomial functions. $f(x) = \dfrac{P(x)}{Q(x)}$ The graph below is that of the function $$f(x) = \dfrac{x^2-1}{(x+2)(x-3)}$$. Because the denominator of $$f$$ given by the expression $$(x+2)(x-3)$$ is equal to zero for $$x = -2$$ and $$x = 3$$, the graph of $$f$$ is undefined at these two values of $$x$$; as we can see that the graph is discontinuous at these values of $$x ... Rational Functions Questions and Answers | Study.com Answers to Questions on Rational Functions.

Newest Rational Functions Questions | Wyzant Ask An Expert A rational function is a fraction of polynomials. That is, if p(x)andq(x) are polynomials, then p(x) q(x) is a rational function. The numerator is p(x)andthedenominator is q(x). Examples. • 3(x5) (x1) • 1 x • 2x 3 1 =2x 3 The last example is both a polynomial and a rational function. In a similar way, any polynomial is a rational function. In this class, from this point on, most of the rational functions that we’ll see Answered: Evaluating Rational Functions Determine… | bartleby † how to graph rational functions and simplify rational expressions. † how to solve rational equations.

Algebra - Rational Functions (Practice Problems) Recall that a rational function is a ratio of two polynomials \(\large{\frac{{P\left( x \right)}}{{Q\left( x \right)}}}\normalsize.$$ We will assume that we have a proper rational function in which the degree of the numerator is less than the degree of the denominator.. In order to convert improper rational function into a proper one, we can use long division:

In mathematics, a rational function is any function which can be defined by a rational fraction, i.e. an algebraic fraction such that both the numerator and the denominator are polynomials.The coefficients of the polynomials need not be rational numbers; they may be taken in any field K.In this case, one speaks of a rational function and a rational fraction over K.
