Chapter 10.5, Problem 13P

Make a table of value and graph each function.

$y=\sqrt{x+2}$

To determine

To graph: the function.

Explanation of Solution

Given information:

The function is $y=\sqrt{x+2}$ .

Graph: to draw the function, use the plotting point method,

$x$	$y$
$-2$	$0$
$0$	$\sqrt{2}$
$2$	$2$
$3$	$\sqrt{5}$

By using the above table and join the points,

The graph can be obtained as:

  

Interpretation: from the above graph it can be observed that the domain of the function is $x\ge -2$ .
