$f$ is a finite function whose domain is the letters $a$ to $e$. The following table lists the output for each input in $f$'s domain.
$x$|$a$|$b$|$c$|$d$|$e$
:-|-:|-:|-:|-:|-:
$f(x)$|$2$|$1$|$0$|$1$|$2$
**Build the mapping diagram of $f$ by dragging the endpoints of the segments in the graph below so that they pair each domain element with its correct range element. **
**Then, determine if $f$ is invertible.**
