Unit G Summary Question 6: Y- Value when its undefined

6. How do we find the appropriate place to plot a hole if the y-value is undefined when plugged into the original equation?
To find the appropriate place to plot a hole when the y value is undefined you have to plug it into the factored equation. When trying to find this exact spot we have to use the factored equation because if we use the original one it can result in a totally different answer. Since we have already factored out our function beforehand, we no longer bring into account the original one. All we need is the factored out rational function to find the rest of the stuff we need to find such as domain, x intercepts, and y intercepts. Its imperative that we don't pay attention to the original function as much because it can effect our answer.
