You can put this solution on YOUR website! graph two periods of the given tangent function
y= 3 tan x/4
---------------
Period would normally be pi.
But since you have x/4 the period is 4pi
-------------------------------------------
Mark -2pi to 2pi on the x axis
Sketch a single swath of tan(x) in that interval.
---
Mark 6pi on the x axis.
Sketch a single swath of tan (x) in the [2pi,6pi] interval.
