Let A = R {3}, B = R - {1}, and let x-2 x-3 f: A B be defined by f(x) = - . Isfinvertible? Explain. Consider a real-valued function f(x) satisfying 2 f(xy) = (f(x)) + (f(y))* \ x,y Randf(1) = a, where a ≈ 1. Prove that (a − 1) Σ ƒ (i) = a™+¹ − a. _n+1 - i=1 The function f(x) is defined for all real x. If ƒ(a + b) =ƒ (ab) & a and b and ƒ (-2) = - the value of ƒ (1005). then find
