In class we considered TC(q) = q^2 + 4. AFC(q) is always decreasing, and AVC(q) is always increasing. Thus, two forces affect average cost: AC(q) = AVC(q) + AFC(q). Is it true that AVC(q) = AFC(q) at the minimum of AC(q) (the two "balance each other")? either prove the result for an arbitrary TC(q) function, or find a counterexample.
Using discrete mathematical proofs: a. Prove that, for an odd integer m and an even integer n, 2m + 3n is even. b. Give a proof by contradiction that 1 + 3√ 2 is irrational.
76.Let p be an odd prime. Prove that if Ord, (a) = his even, then a/2 = -1 mod p. 77.let p be an odd prime. Prove that if Ord, (a) = 3, then 1+ a + a? = 0 mod p and Ord,(1 + a) = 6. 78.Show that 3 is a primitive root modulo 17. How many primitive roots does 17 have? Find them.
Prove that the following premise
4. Prove the following: (a) Prove that n is even if and only if n2 6n+5 is odd. (b) Prove that if 2n2 +3n +1 is even, then n is odd.
Assume n is an integer. Prove that n is odd iff 3n2 + 4 is odd. Remember that to prove p iff q, you need to prove (i) p → q, and (ii) q → p. Use the fact that any odd n can be expressed as 2k + 1 and any even n can be expressed as 2k, where k is an integer. No other assumptions should be made.

4. Consider the sequence {z,.) such that z1-0, z2-1 and æn-telths,Yn (i) Show that (n) is convergent by showing that the subsequence of odd-indexed terms is monotonic increasing and subsequence of even-indexed terms is monotonic decreasing (ii) Find the limit of {%) (Hint: Consider x,-h-i)
