Unit G Summary Questions #6 Finding Holes

6.How do we find the appropriate place to plot a hole if the y- values is undefined when plugged into the original equation?

Note: Not all equations will have holes.

To get a hole the factors of your verticle asymptote must cancel. The canceled portion is what becomes your holes. Now to get your missing y- value you have to plug in your hole to the simplified factored equation. We have to remember to plug it into the simplified one, Not Your Original Equation.  After all this process you plot your point as an OPEN CIRCLE on the graph. The rest of our points on the graph will be closed circles.
