Suppose that F1 ο G2 =F1ο G1 then F : S→ T, G1 : T → U, G2 :T →U,. Define a function F : R2 ? R2 by F(x, y) = (x +y, x - y). . Show that if F is onto, Suppose that G1ο F = G2 ο F. Show by counter example that if F isnot onto then show that if H is one-to-one, then G1 = G2. Butthis means one of two things, H is not one to one, and if andonly if t=g.
