Question

For the function given by the graph, which among the following option(s) is/are true

Answer 1

From the graph, it can be observed that maximum value is $1$ and minimum value is $-3$
So, Range will be $[-3,1]$
As the values of the function are repeating after every interval of $2\pi$,so period is $2\pi .$

Since, $4\pi$ be a multiple of $2\pi ,$ so $4\pi$ can also be the period of the given function.
