Rational functions are those functions that are the division of two polynomials,the The rational inequality is an inequality which contains a rational expression, while the horizontal asymptote of a rational function can be determined by looking at the degrees of the numerator and denominator.Intercepts are the points at which a graph crosses either the x or y axis, and they are very useful in sketching functions. Lastly,The x -intercepts (also known as zeros or roots ) of a function are points where the graph intersects the x -axis. Rational functions can have zero, one, or multiple x -intercepts.
