Let f(n) = 5n2 + 8n + 3. Show that f(n) is O(n2). Be sure to specify the values of the witnesses C and k.(Please note: For all the questions in this exam, show all the necessary steps for each question to get the full points for the question, otherwise providing just the answer does not attract any points without providing the complete proof, or computation or justification of all the steps of your solution.)
