See a solution process below:

#### Explanation:

$x$ can take any value without violating any rules of math.

Therefore, the domain, or input, for this function is the set of all Real numbers: $\left\{\mathbb{R}\right\}$

Because this is a linear transformation, the range, or output, for this function is also the set of all Real numbers: $\left\{\mathbb{R}\right\}$
