Find the ranges of \(f\) and \(g\), and sketch the graph of \(g\).
Determine the solution sets of the equations
- \(f(x) = g(x),\qquad\) (ii) \(fg(x) = g\,f(x)\).

Question
For any real number \(x\), \([x]\) denotes the greatest integer not exceeding \(x\); e.g. \([3.6] = 3\), \([2] = 2\), \([-1.4] = -2\), etc. Functions \(f\) and \(g\) are defined on the domain of all real numbers as follows:
\[\begin{equation*}
f \colon x \to [x]; \quad g \colon x \to x - [x].
\end{equation*}\]
