Calculate the big-O estimates for the following functions: (n? +n)(n2 +1000) (n log? n +n)(na +na) (2n + n)(n +2) (n + n2 log n)(1+ log n) + (n + log? n)(n +1) (2n! + 22")(n! +nn) (n log? n + n logn)(1+ log n + log? n + logn)(1+ log n3) (n + m2 +n3) (2logn + 2log? n + 2logn) (1+n + n)(n +n4 +no) m=1 k3 = log* 111(1 + log n)
