10. Based on this graph of y = a*, (A) limx-+04 27 = 1 (B) limr-40- 27 = 1 (C) lime-ox is a number slightly less than 1. (D) limx-+0- 2 = 2. 11. lim2-+2- 2. 3 -8 x - 2 (A) 12 (B) -2 (C) exists but it is equal to a number not listed here (D) the limit does not exist since the denominator is 0 when x = 2 . 12. As x -> 2 , the values of f(x) approach -3. However, as x - 2+ the values of f (x) do not approach any particular number. Which of the statements is then correct? (A) limx-+2- f(x) = -3 but neither limx-2+ f(x) nor limx-2 f (x) exists. (B) limx-+2+ f(x) = -3 (C) lima-2 f(x) = -3 (D) All above are incorrect
