WebExplanation: . Factorize the numerator for the function: The removable discontinuity is since this is a term that can be eliminated from the function. There are no vertical asymptotes. Set the removable discontinutity to zero and solve for the location of the hole. WebFinding the Domain of a Rational Function Find the domain of f(x) = x + 3 x2 − 9. Analysis A graph of this function, as shown in Figure 8, confirms that the function is not defined when x = ± 3. Figure 8 There is a vertical asymptote at x = 3 and a hole in the graph at x = −3.
