I have the following example, I don't get what is being done here, how are the subsets of A taken? and the images? please show the example in more steps: "For A={a,b,c,d,e} and B={1,2,...,6} f={(a,3),(b,5),(c,2),(d,3),(e,6)} is a function from A to B. For C1={a,b,c}, C2={a,d}, C3={e} and C4=A, f(C1)={2,3,5}, f(C2)={3}, f(C3)={6}, f(C4)=range(f)={2,3,5,6}"
