(a) It can be shown that the inequalities 1 - < 1 hold for all values ofx close to zero (exceptfor x- 0). What, if anything, does this tell you about lim end y: 1 together for - 2 sx Comment on the behavior of the graphs as x x sin x Q Give reasons for your answer 2-2 cos (b) Graph y 1 xsmx 2-2 cosx (a) Choose the correct answer below 22 cosx x smx 2-2 cos O A. 1m O B. 1m O C. 1m x smx is 1 because 11m 22 cos x smx is 0 because 11m 22 cos x smx does not exist. 22 cos = lim 1. X Sin x 22 cosx lim 1 lim (b) Choose the correct graph below Comment on the behavior of the graphs as Choose the correct answer below O A. As xO, the graphs of all three functions are away from each other. x sin x As x*o, the graphs of the functions 1 and 1 are close to each other Out the graph of approaches infinity 2-2 cosx 0, the graphs of all three functions are close to each other
