Chapter 1.2, Problem 5.4E

In general, let us denote the identity function for a set $C$ by $i_C$. That is, define $i_C:C\to C$ to be the function given by the rule $i_C\left(x\right)=x$ for all $x\in C$. Given that $f:A\to B$, we say that a function $g:B\to A$ is a left inverse for $f$ if $g\circ f=i_A$; and we say that $h:B\to A$ right inverse for $f$ if $f\circ h=i_B$.

Can a function have more than one left inverse? More than one right inverse?
