Suppose $f(x) = (x + 1)^2$ for $x \ge -1$. If $g(x)$ is the function whose graph is the reflection of the graph of $f(x)$ with respect to the line $y = x$,then $g(x)$ equals

  • A
    $-\sqrt{x} - 1, x \ge 0$
  • B
    $\frac{1}{(x + 1)^2}, x > -1$
  • C
    $\sqrt{x + 1}, x \ge -1$
  • D
    $\sqrt{x} - 1, x \ge 0$
