Question:

We explore functions whose graphs approach a nonhorizontal line as x → ∞. A line y = ax + b is called a slant asymptote if

or lim (f(x) (ax+b)) = 0 X-00 lim (f(x) (ax + b)) = 0 X--0

Show that y = 3x is a slant asymptote for ƒ(x) = 3x + x−2. Determine whether ƒ(x) approaches the slant asymptote from above or below, and make a sketch of the graph.
