Statement II is not a correctUse binomial theorem ( a − b) 2 = a 2 − 2 a b b 2 to expand ( x − 2) 2 fx=9\left (x^ {2}4x4\right) ∣ f ∣ x = 9 − ( x 2 − 4 x 4) To find the opposite of x^ {2}4x4, find the opposite of each term To find the opposite of x 2 − 4 x 4, find the opposite of each term fx=9x^ {2}4x4Now suppose that x1,x2 ∈ Z and f(x1) = f(x2) Then x1 5 = x2 5 and thus x1 = x2 It follows that f is onetoone Consequently, f is a bijection Notice that if a function f X → Y is a onetoone correspondence, then it associates one and only one value of y to each value in x In particular, it makes sense to define a reverse function
