Answer: OPTION B
Step-by-step explanation:
You can observe in the graph of the function given, it begins to decrease from --3π/2 to -π/2. Then it increases again to y=3, where it reaches it maximum point, this is when x=kπ/2 (With k an odd integer: 1,3,5,7...)
Finally, it begins to decrease again from π/2 to 3π/2.
Therefore, the answer is the option B.
