Unit G Summary Question #6 Plotting Holes

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

• When the y-value is undefined when plugged into the original equation, there is no hole to plot. When we do have a hole to plot, we take the canceled factors of the vertical asymptotes equation. we equal those to zero. We will get the x-value from there. Next, as we plug the value back to the original equation , thus getting the y-value. Finally, simply plot the hole on the graph. Make sure it is a HOLE.
