The function is $\"f(x)=2^{-x}\"$ .

Make the table of values to find ordered pairs that satisfy the function.

Choose values for $\"x\"$ and find the corresponding values for $\"y\"$ .

$\"-4\"$	$\"f(-4)=2^{-(-4)}=16\"$	$\"(-4,$
$\"-3\"$	$\"f(-3)=2^{-(-3)}=8\"$	$\"(-3,$
$\"-2\"$	$\"f(-2)=2^{-(-2)}=4\"$	$\"(-2,$
$\"0\"$	$\"f(0)=2^{(0)}=1\"$	$\"(0,$
$\"2\"$	$\"f(2)=2^{-(2)}=0.25\"$	$\"(2,$

Graph :

Graph of the function $\"f(x)=2^{-x}\"$ .

1. Draw a coordinate plane.

2. Plot the coordinate points.

3. Then sketch the graph, connecting the points with a smooth curve.

$\"\"$

Domain of the function is all real numbers.

Range of the function is $\"(0,$ .

$\"x\"$ - intercepts is $\"0\"$ .

$\"y\"$ - intercepts is $\"0\"$ .

End behavior : $\"\\lim_{x\\rightarrow$ and $\"\\lim_{x\\rightarrow$ .

Decreasing interval : $\"(-\\infty,$ .
