Chapter 3, Problem 1CA

To determine

To find; the values can use for $x$ and $y$ to support the claim, and to find the values that friends use.

Answer to Problem 1CA

$x$	$-4$	$-2$	$-1$	0
$y$	1	3	4	5

Explanation of Solution

Given information:

Given table

Calculation:

The values of table of your claim

$x$	$-3$	$-2$	$-1$	0
$y$	2	3	4	5

In the above table the $y$ increase by 1unit and the $x$ increases by 1 unit so the rate of change in $y$ and $x$ is constant hence this is a linear function.

The values of the table of your friend

$x$	$-4$	$-2$	$-1$	0
$y$	1	3	4	5

In the above table the $y$ increases by different units and the $x$ increases by different units so the rate of change in $y$ and $x$ is not constant hence this is a nonlinear function.
