A rational function is defined as quotient of two polynoials of p(x) and q(x). The domain of the rational function must be all reals except the roots of the equation q(x)=0. The range of rational functions can be found by finding minimum values of the function. In case p(x) and q(x) have a common factor x-beta . Then after cancelling the common factor. The rational functional must assume a value of x=beta which should be delete from the range since beta is not in the domain of the rational function The range of rational function f(x)=(2x^(2)+5x+2)/(2x+1)
