1-146.

Each of these functions has one or more holes and/or asymptotes. Graph them on your graphing calculator and write a complete set of approach statements for each function.

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

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

A complete set of approach statements will include:

$x → ∞$

$x →$ (hole)$^−$

$x →$ (vert. asymptote)$^−$

$x → −∞$

$x →$ (hole)$^+$

$x →$ (vert. asymptote)$^+$
