Let A = {x, y} and let S be the set of all strings over A. Define a relation C from S to S as follows: For all strings s and t in S, (s, t) E C means that t= ys. Then C is a function because every string in S consists entirely of x's and y's and adding an ad- ditional y on the left creates a single new string that consists of x's and y's and is, therefore, also in S. Find C(x) and C(yyxyx).
