How to evaluate a rational function given three different input values

The video tutorial explains how to evaluate a function F(x) = 5 / (1 - x) for different values of x. It provides examples for x = -2, x = 0, and x = 1, demonstrating the calculation process and highlighting the concept of undefined results when dividing by zero. The tutorial emphasizes the importance of understanding these concepts in function evaluation.
