Question 91176: 2) By looking at the equation for a rational function, how can you tell if there will be "y-values" which will never occur? How might this be represented on the graph? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! The denominator of the rational function cannot have a value of zero.
If there are radicals in the denominator the radicand must not be negative.
