Answer
Refer to the curve in Black in Graph I
Work Step by Step
For $f(x) = \sqrt{x + 2}$
when
$x = 7, y = 3;$
$x = 2, y = 2;$
$x = -1, y = 1;$
$x = -2, y = 0$
As seen, $f(x) = \sqrt{x + 2}$ is the horizontal translation to the left by 2 units of $f(x) = \sqrt{x}$.
Domain = $[−2, \infty)$
Range = $[0, \infty)$
