Determine Whether the Graph of the Rational Function Has a Horizontal

Multiple Choice

Determine whether the graph of the rational function has a horizontal asymptote, an oblique asymptote, or neither. Give
the equation of the asymptote if it exists.
- $f ( x ) = \frac { x ^ { 2 } + 4 x - 6 } { x - 2 }$

A) Horizontal asymptote: y = -2
B) Oblique asymptote: y = x + 6
C) Neither
