Graphing Rational Functions with Holes

Rational functions have points where they are undefined, which introduces us to graphing holes in the function. Graphing holes involves being able to find these points. A rational function is a quotient of two functions, and if the denominator of this quotient has zeros, the rational function is undefined at that point. Graphing holes means showing what input values makes this denominator function zero.
