please help me with #5, #6, #7, #8
5. Let f: Râ R be defined by f(x)= 2-3. Prove that f is a bijection. 6. Let G be a group and let a E G. Prove that the function f : G â G defined by f(x) = a * x is a bijection (Note that if G is a finite group this gives an alternate proof of the fact that each element of G appears precisely once in each row of the group table of G.)
