1-71.

Find the domain of each of the following functions.

1. $f ( x ) = \sqrt { x + 2 }$

If the domain of the parent graph, $y=\sqrt{x}$, is $x\ge 0$, what is the domain of $f(x)$?

1. $f ( x ) = \frac { 1 } { x - 4 } + 3$

If the domain of the parent graph, $y=\frac{1}{x}$, is $x \neq 0$, what is the domain of $f(x)$

1. f(x) = log (x − 4)

If the domain of the parent graph, $y=\text{ log}{x}$, is $x > 0$, what is the domain of $f(x)$?

1. $f ( x ) = \sqrt { \frac { 2 - x } { x } }$
