Formal proof and state which proof style you use
Let a function where f:Z5 → Z5 defined by f(x) = x3 (mod5). a. Is f an injection? Prove or provide a counter example. b. Is fa surjection? Prove or provide a counter example. c. Find the inverse relation of f. Verify that it is the inverse, as we have done in class. d. Is the inverse of f a function? Explain why it is or is not a function.

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:

"Proof by Mathematical Induction" is an important technique to know. We can use this technique to prove the following equation: 12+32+52 +(2n+1)2 (n+1) (2n+1) (2n+3)/3 note: n starts at 0, I.E. n 0, 1, 2, 3... To do so: (1) What is the basic step? (state the basic step, and write it using the formula above) (2) What is the inductive step? (state the inductive step, and write it using the formula above) you don't need to prove it, just...

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...
