- 1. What is domain?
A) Are all the values in X B) Are all the values in X and Y C) Are all the values in X D) None - 2. What is range?
A) All the values in Y B) Are all the values in X and Y C) Are all the values in X - 3. The graph is discontinuous
A) Because of symmetry B) Because has a hole C) None D) Because has a Asymptote E) Because has a jump - 4. The domain is
A) ] - ∞, + ∞ [ B) R C) Both are correct - 5. The domain is
A) ]-∞, 3] U [3,+ ∞[ B) ]-∞, -3] U [-3,+ ∞[ C) ]-∞, -3] U [3,+ ∞[ D) All of them are correct - 6. The graph is….
