CPM Homework Help : CALC Problem 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.

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

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

Hint (a):

A complete set of approach statements will include:

$x → ∞$

$x →$ (hole)^{$^−$}

$x →$ (vert. asymptote)^{$^−$}

$x → −∞$

$x →$ (hole)^{$^+$}

$x →$ (vert. asymptote)^{$^+$}

Hint (b):

See the hint in part (a).
