PS:Please help me doing them prefectly on a word processing document. 2. Let f: Z²Z² be given by f(m, n) = (m-n, n). The composite functions fk, for k € Z+, aredefined as fi(m, n) = f(m,n), and fk+1(m, n) = f(fk(m, n)), for k € Z+. Give a formal proofby induction that f(m, n) = (m-kn, n), for all k € Zt.

We use the process of mathematical induction
