Determining if a Relation is a Function

Determining if a Relation is a Function 1.2 - Solution

Return to Determining if a Relation is a Function

A table of values shows the coordinates for a few, or all, points on a function graph. We're given the $x$ -values that should be included in the table. Let's substitute them into the function rule to find their corresponding $y$ -values.

$x$	$3 x - 2$	$y$
$0$	$3 \cdot 0 - 2$	$- 2$
$1$	$3 \cdot 1 - 2$	$1$
$2$	$3 \cdot 2 - 2$	$4$
$3$	$3 \cdot 3 - 2$	$7$

The final table of values consists of the $x$ - and $y$ -column.

$x$	$y$
$0$	$- 2$
$1$	$1$
$2$	$4$
$3$	$7$
