What is the equation of the graph?
True or False?
Rational functions can have more than one vertical asymptote.
True, each vertical asymptote is obtained by setting the factors of the denominator = 0.
True, each vertical asymptote is obtained by setting the factors of the numerator = 0.
False, there can be only one determined by the power of the numerator compared to the power of the denominator.
True or False?
The graph of a rational function can cross a horizontal asymptote.
True, a graph can cross a horizontal asymptote because it really dictates the end behavior.
