Consider the inequality cos(2x) < 0; period [0,*).
Milan wants to find the solution set for the inequality. She begins by finding the zeros for cos(2x) : x = 4.x = **.
and x =
Then, she studies the intervals (0,4),(4, 34), and (**), and determines where cos(2x) <0 or cos(2x) > 0 by
picking a value for x from each interval. She finds the following.
cos(2x) > 0 from 0 to 4
cos(2x) < 0 from to
cos(2x) > 0 from * to
Finally, Milan concludes that cos(2x) < 0 on the interval [4, 34).
Part A: Which answer choice shows the correct analysis of Milan's work?
Part B: What is the domain of the inequality?
Part C: What is the solution set for the inequality?
Select one answer for Part A, one answer for Part B, and one answer for Part C.
