there is a vertical asymptote

• when the denominator equals zero
• when the degree of the numerator is exactly one more than the denominator
• when there is a common factor in the numerator and denominator
• when the degree of the numerator is the same as the denominator

There is a hole in the graph

• when the numerator and denominator have a common factor
• where the denominator equals zero
• if the degree of the numerator is exactly one more than the denominator
• if the degree of the numerator and denominator are the same.

You determine if the graph has a horizontal asymptote by

• setting the denominator equal to zero and solving
• comparing the degree of the numerator and denominator
• dividing the numerator and denominator
• determining if the numerator and denominator have a common factor.
