I believe #3\pi(x)# means #3\pix#, this notation doesn't make any other sense to me.
If so, the period must be #1/3#.

We know that the period of #tan(\theta)# is #\pi#, and we know that adding a constant and multiply by a constant outside doesn't change the period.
So it must be the same period of #tan(3\pix)#, which is trivially #1/3#
