My students, well, kind of half-failed, unfortunately.
1. What is the domain of the function ln(x)?
2.Give answers to the following questions (yes/no) with short explanations
- Is the set {(0,0)} a binary relation on ℕ?
- Define an operation on sets like this: A Op B = {{A}, {B}}. Do we have a commutative monoid?
- Take the set {1,2,7} and define an operation like this: x Op y = x. Is it a monoid?
3. Is implication operation, P→Q, associative? Commutative? Does it have a neutral element?
4. Simplify the following WFF: C ∨ (A→B) ∨ (B→A) ∨ C
5. Convert the following WFF to DNF: (A∨B)∧(C∨¬B)∧(¬A∨C)
