To establish a big-O relationship, find witnesses C and k such that | f(x) | C | g(x) | whenever x>k. Find the least integer n such that f (x) is O (xn) for the function f (x) = (x3 + 5log x) / (x4 +1).

Answer and explain

To establish a big-O relationship, find witnesses Cand k such that|f(x)|SC|g(x) | whenever x>k. Find the least integer n such that f(x) is 0 (x") for the function f(x) = (x3 + 5log x)/(x4 +1). On=-1 with witnesses C = 6 and k = 1 O n=1 with witnesses C = 6 and k = 0 On=1 with witnesses C = 6 and k = 1 On=-1 with witnesses C= 6 and k = 0
