Coordinates of a Hole of a Rational Function. In this video, I show how to find the coordinates of a hole in the graph of a rational function.
The basic idea is to factor as much as possible and simplify.
Any value of x that made the original function produce 0/0 can now be put into the simplified version to find the coordinate of the hole.
Note that even though the simplified function will be defined at the value, the original function IS NOT and so there is a hole.
