ANSWERS1. Answer to Question 1 is ”D”.If log b x = y then b y = x.Go back 12. Answer to Question 2 is ”A”.Go back 23. Answer to Question 3 is ”A”.Go back 34. Answer to Question 4 is ”A”.Go back 45. Answer to Question 5 is ”C”.Go back 56. Answer to Question 6 is ”B”.Go back 67. Answer to Question 7 is ”A”.y = log 2 (x + 1) can be re-written as 2 y = x + 1 or 2 y − 1 = x. If y = 0then 2 0 − 1 = x or x = 0. If y = 1 and then 2 1 − 1 = x or x = 1. Ify = −1 then 2 −1 − 1 = x or x = − 1 2 .Go back 77

8. Answer to Question 8 is ”A”.Go back 89. Answer to Question 9 is ”D”.If y = −0.28 then e −0.28 = y. Thus, y = 0.7558.Go back 910. Answer to Question 10 is ””.Go back 1011.
