Chapter 3, Problem 25PT

To determine

To graph: the given function.

Explanation of Solution

Given information:

The function $f(x)=[[x]]$

The given function is the greatest integer function. The value of the greatest integer

function is the largest number that is less than or equal to the given decimal.

Make a table of values for $f(x)=[[x]]$

$x$	$-1$	$-0.5$	$0$	$0.5$	$1$
$g(x)$	$-1$	$-1$	$0$	$0$	$1$

Graph:

The graph of $f(x)=[[x]]$ is shown below.
