to show that f(x) = O(g(x)) we have to find a +ve constant C and k such that f(x)<=Cg(x) for all x> k
to find the smallest element we have to traverse through all the elements at least once, which makes this an O(n) algorithm
QUESTION 3 To show that f(x) is O(g(x) using the definition of big o, we find...
[12 marks] Using the definition of big-O, show that f(x) is big-O of g, where: f(x) = 2* + 33 and g(x) = 3* Show the details of your work to obtain a full mark.
#1. Using the definition of big-O, prove that f(x) = 5x^4+x^3+8x-2 . Show all work. #2. void bubbleSort(Student myClass[], int size) { int pass = 0; // counts each pass of the sort bool done = false; // whether sorted or not // each pass puts one element into its sorted position, // smallest value bubbles to the top of the array while (!done) { done = true; // possibly sorted // compare consecutive elements, swap if out of order...
1. [5 marks Show the following hold using the definition of Big Oh: a) 2 mark 1729 is O(1) b) 3 marks 2n2-4n -3 is O(n2) 2. [3 marks] Using the definition of Big-Oh, prove that 2n2(n 1) is not O(n2) 3. 6 marks Let f(n),g(n), h(n) be complexity functions. Using the definition of Big-Oh, prove the following two claims a) 3 marks Let k be a positive real constant and f(n) is O(g(n)), then k f(n) is O(g(n)) b)...
7. Let f(x) = 3x + 4. We know that f(x) is big-O of x2. Find the lowest k that works for C = 1 and justify your answer fully. Note that you have to show two aspects: your k works and the no lower k value work. Important: you must show all work on free response questions. If the question asks you to prove something, you must write a proof as explained in the presentations and additional handouts on...
Formal Definitions of Big-Oh, Big-Theta and Big-Omega: 1. Use the formal definition of Big-Oh to prove that if f(n) is a decreasing function, then f(n) = 0(1). A decreasing function is one in which f(x1) f(r2) if and only if xi 5 r2. You may assume that f(n) is positive evervwhere Hint: drawing a picture might make the proof for this problem more obvious 2. Use the formal definition of Big-Oh to prove that if f(n) = 0(g(n)) and g(n)...
State the definition of “f(x) is O(g(x))” and use the definition to show that x 2 + 3x is O(x 3 ). Please show as much work as possible. Thanks.

Question 23 . > 1 if x = 3 and f(x) = x2 – 3 and g(x) = then g(f(x)) Find the following given: f(x) = x2 + 3 and g(x) = x – 2 f(g(x))= Submit Question
(5) The following is the formal definition for O-notation, written using quantifiers and variables: f(x) is (g(x)) if, and only if, 3 positive real numbers k and C such that Vu > k, |f(x) <C|g(2) Write the negation for the definition using the symbols V and 3.
7. Show all work to answer the following question. If the area enclosed by x = y2 – 4 and x = k where k > 0 is equal to 12, find the value of k. To earn any credit for this question you must use strategies
