$y=2+\sqrt {5-x}$
This graph is a function since it passes the vertical line test.
Work Step by Step
The graph of $y=\sqrt x$ has a domain of [0, infinity) and a range of [0, infinity). Adding 2 to the function changes the range to [2, infinity). Changing the variable from $x$ to $5-x$ changes the domain to (-infinity, 5].
