$f\left( x \right) = \left[ x \right] + \left| {1 - x} \right|,\, - 1 \le x \le 3$ કે જ્યાં $[x]$ એ મહતમ પૃણાંક વિધેય છે .
વિધેય $1$ :$f$ એ $x = 0, 1, 2$ અને $3$ આગળ સતત નથી.
Statement $2$ :$f\left( x \right) = \left( \begin{array}{l}
- x,\,\,\,\,\,\,\,\,\, - 1 \le x < 0\\
1 - x,\,\,\,\,\,\,\,0 \le x < 1\\
1 + x,\,\,\,\,\,\,\,1 \le x < 2\,\\
2 + x,\,\,\,\,\,\,2 \le x \le 3
\end{array} \right.$
