Find the range of the following function:
$f(x) = x$,where $x$ is a real number.

(N/A) Given the function $f(x) = x$,where $x \in \mathbb{R}$.
By definition,the range of a function is the set of all possible output values (images) for the given domain.
Since $x$ can be any real number,the output $f(x)$ will also be any real number.
Therefore,the range of $f$ is the set of all real numbers,denoted by $\mathbb{R}$.
