For each of the statements below, state whether it is true or false. If true, explain why each of its directions → and ← is true. If false state which direction is false and give a counterexample. (a) ∀x (A(x) ∨ B(x)) ↔ ∀xA(x) ∨ ∀xB(x) (b) ∀x (A(x) ∧ B(x)) ↔ ∀xA(x) ∧ ∀xB(x) (c) ∃x (A(x) ∨ B(x)) ↔ ∃xA(x) ∨ ∃xB(x) (d) ∃x (A(x) ∧ B(x)) ↔ ∃xA(x) ∧ ∃xB(x)

Write true or false for each of the following statements. Provide justification for each answer—if true, give a brief explanation. If false, either provide a counterexample or contrast the statement with a similar true statement, explaining why the two cases differ.

Question 5 20 pts Indicate whether the following statement is true or false. In order to receive full credit, you must provide justification of your answer on the separate sheet you submit(e.g., a proof of a true statement, or a counterexample to a false statement). If f is a continuous function on a smooth curve C in the xy-plane and Sc f(x,y) ds > 0, then f(x,y) > 0 for all points (x, y)...

Problem 1: Determine whether the statement is true or false. If the statement is true, then prove it. Otherwise, provide a counterexample. (a) If a continuous function f:R +R is bounded, then f'(2) exists for all x. (b) Suppose f.g are two functions on an interval (a, b). If both f + g and f - g are differentiable on (a, b), then both f and g are differentiable on (a,b). Problem 2: Define functions f,g: RR by: x sin(-),...
