Write a complete set of approach statements for the following functions. Also, write the equations of any end-behavior functions.

1. $f ( x ) = \frac { x ^ { 2 } - 2 x - 3 } { x - 2 }$

   Hint (a):

   A complete set of approach statements will include:
   $x→+∞$
   $x→−∞$
   $x→\left(\text{hole}\right)^{−}$
   $x→\left(\text{hole}\right)^{+}$
   $x→\left(\text{vertical asymptote}\right)^{−}$
   $x→\left(\text{vertical asymptote}\right)^{+}$

   Hint (a):

   If a function has a horizontal asymptote, then that is also the end behavior.

2. $f ( x ) = \frac { \operatorname { cos } ( x ) } { x }$

   Hint (b):

   Refer to hint in part (a).
