Answer
$\bf \color {blue}{(0,-3),(9,0),(1,-2)}$
Work Step by Step
$$\bf{y=\sqrt{x}-3}$$
$\bf \text{Lets plug in numbers to find three points}$
if $x=0$:
$y=\sqrt{0}-3$
$y=-3$
$\bf \color {blue}{(0,-3)}$
if $y=0$:
$0=\sqrt{x}-3$
$3=\sqrt{x}$
$x=9$
$\bf \color {blue}{(9,0)}$
if $x=1$:
$y=\sqrt{1}-3$
$y=1-3$
$y=-2$
$\bf \color {blue}{(1,-2)}$
So three of the points are:
$\bf \color {blue}{(0,-3),(9,0),(1,-2)}$
Which we can graph as:
