Prove your answers for 11 15 from the quia quiz only (questions copied below), using the definition of Big-Theta. All you need to do in your proof is to clearly state what c and no you choose for the True answer (these constants do not have to be the same for big-O and big-Theta) or explain as rigorously as possible why such constants cannot be chosen. Put your answers in HW5-Answers.pdf file. 12. + log 64-6(1) 13. n log n + n =0(log n) 14, 2n + n = (n) 15. + log n = (r)
