Write a formal proof to prove the following conjecture to be true or false. If the statement is true, write a formal proof of it. If the statement is false, provide a counterexample and a slightly modified statement that is true and write a formal proof of your new statement. Conjecture: 15. (12 pts) Let h: R + RxR be the function given by h(x) = (x²,6x + 1) (a) Determine if h is an injection. If yes, prove it....

(b) Show that the following statement is false: n-n is a multiple of 4 for all n 2 1. Question 4-10 ma You should be able to answer this question after studying Unit 9. (a) Use proof by...
(a) Suppose you wish to use the Principle of Mathematical Induction to prove that n(n+1) 1+ 2+ ... +n= - for any positive integer n. i) Write P(1). Write P(6. Write P(k) for any positive integer k. Write P(k+1) for any positive integer k. Use the Principle of Mathematical Induction to prove that P(n) is true for all positive integer n. (b) Suppose that function f is defined recursively by f(0) = 3 f(n+1)=2f (n)+3 Find f(1), f (2), f...
Problem 1 148pts] (1) I 10pts! Let P(n) be the statement that l + 2 + + n n(n + 1) / 2 , for every positive integer n. Answer the following (as part of a proof by (weak) mathematical induction): 1. [2pts] Define the statement P(1) 2. [2pts] Show that P(1 is True, completing the basis step. 3. [4pts] Show that if P(k) is True then P(k+1 is also True for k1, completing the induction step. [2pts] Explain why...
11: I can identify the predicate being used in a proof by mathematical induction and use it to set up a framework of assumptions and conclusions for an induction proof. Below are three statements that can be proven by induction. You do not need to prove these statements! For each one clearly state the predicate involved; state what you would need to prove in the base case; clearly state the induction hypothesis in terms of the language of the proposition...
2: Use mathematical induction to prove that for any odd integer n >= 1, 4 divides 3n + 1 ====== Please type / write clearly. Thank you, and I will thumbs up!
Main topic and problems for the final project The main purpose of the project is to introduce you how to use a in an computer as a research tool Introductory Discrete Mathematics. In this project you will be asked to show how the Fibonacci sequence {Fn} is related to Pascal's triangle using the following identities by hand for small and then by computers with large n. Finally, to rove the identity by mathematical arguments, such as inductions or combinatorics. I...
