Answer
Domain = $\mathbb{R}\backslash\{5\}$ or $\{x\in \mathbb{R}\ |\ x\neq 5\}$,
Range = $\mathbb{R}\backslash\{2\}$ or $\{y\in \mathbb{R}\ |\ y \neq 2\}$
Work Step by Step
The range is the set of all second coordinates.
The empty dot at $(5,2)$ indicates that the point does not belong to the graph.
The first coordinate of a point of the graph can be any real number, except $5$.
Domain = $\mathbb{R}\backslash\{5\}$ or $\{x\in \mathbb{R}\ |\ x\neq 5\}$,
The second coordinates can be any real number, except $2$.
Range = $\mathbb{R}\backslash\{2\}$ or $\{y\in \mathbb{R}\ |\ y \neq 2\}$
