Check the answer that best describes the relationship between f(x) and x. (For example if f(x) is (z) check that as your answer and not 0(z) or (z) even though these are true also in this case.) (a) f(x) 10 is A, (z) o B. O(x) C. (z) (b) f(x)- 3z 7 is A. (z) B. (z) o C. O(E) (c) f(x)2+z +1 is A. (z) o B. O(E) (d) f(x)-5 log(x) is o A. O(x) B. (z) C. (z) (e) f(z) = 1 is O A. O(z) B. (z)
