The subject matter of this work is the set of integral points(i.e. pointswith both coordinates integers) on the graphs of rational functions of the formf(x)=(x^2+bx+c)/(x+a), with a,b,c,being integers.Following the introduction, weestablish Proposition1 in Section2. This proposition plays a key role in theproof of Theorem1 in Section5. Proposition1 is proved with the aid of Euclid'slemma and another well known result in number theory; see reference [1].InSections3 and4, we focus on the special case b^2-4c=0; which implies b=2d andc=d^2, for some integer d. If d and a are distinct; then there are finitelymany integral points, parametrically described in Results1 and2. Theorem1 inSec.5 deals with the general case.Accordingly, if a^2-ab+c is not zero; thereare exactly 4N distinct integral points parametrically described.Except in thecases where a^2-ab+c is a perfect square, or minus a perfect square; in whichcases thare are exactly 4N-2 distinct integral points. Here N stands for thenumber of positive divisors, not exceeding the square root of the absolutevalue of a^2-ab+c. (divisors of that absolute value).The paper concludes withTh.2, which is a direct application of Th.1 in the cases where the aboveabsolute value is 1, p, or p^2; p a prime.
