Question Details:
Suppose
that F1 ο G2 =F1 ο 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 G1 ο F = G2 ο F. Show by counterexample that if F is
not onto then show that if H is one-to-one, then G1 = G2. But this
means one of two things, H is not one to one, and if and only if t=g. πσ
