The directions for the problem state: The following rational functions each have a hole at the given x value. Find the corresponding y value of this point of discontinuity.
I can see how the x value given makes the numerator and denominator zero. But I am confused because in past problems we have done, the holes always had to be a cancelled out factor after we simplified the problem. How do I go about finding y in a problem like this?
Thanks for any help
