Consider the function $f(x) = [x] + |1 - x|$ for $-1 \le x \le 3$,where $[x]$ is the greatest integer function.
Statement $1$: $f$ is not continuous at $x = 0, 1, 2$ and $3$.
Statement $2$: $f(x) = \begin{cases} -1 - x, & -1 \le x < 0 \\ 1 - x, & 0 \le x < 1 \\ 1 - x, & 1 \le x < 2 \\ 2 + x - 2, & 2 \le x < 3 \\ 3, & x = 3 \end{cases}$ (Note: The provided Statement $2$ in the prompt is incorrect).

  • A
    Statement $1$ is true; Statement $2$ is false.
  • B
    Statement $1$ is true; Statement $2$ is true; Statement $2$ is not a correct explanation for Statement $1$.
  • C
    Statement $1$ is true; Statement $2$ is true; Statement $2$ is a correct explanation for Statement $1$.
  • D
    Statement $1$ is false; Statement $2$ is true.
