Oblique Asymptotes: Another Example (4.9.6)

Question 1

• An oblique asymptote is an asymptote that is a slanted line (the line is neither vertical nor horizontal). The equation of this asymptote is the quotient (ignoring the remainder) when the numerator is divided by the denominator in a rational function where the numerator’s degree is equal to the denominator’s degree + 1.

Question 2

• The graph of a rational function will contain a hole if a factor is removed from the denominator when the function is written in simplest form. The x-coordinate of a hole is found by setting each of the denominator’s removed factors equal to 0 and solving for x.
