Unit G #6 Graphing Holes

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

We find out where to plot a hole when y is undefined and then we plug in a zero for x. After doing that, the the remainder would be the value of x and you put the points for the graph. If you plug in zero for x than your y-intercept will be equal to the holes. When y is undefined that means that those are the holes, which is the same as the y-int.
