What is the period of the function f(x) shown in the graph?

Answer:
[tex]\dfrac{\pi }{2}[/tex]
Step-by-step explanation:
The period of the function is from one peak to the next (or from one trough to the next).
[tex]\sf \implies period=\dfrac{\pi }{2}[/tex]
**see attached for the measurement of the period for this function**
