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