State the period, phase shift, and vertical shift of the function y=tan(theta/2pi/4)+3.
Is this right?
ANSWER: period:2pi
phase shift:pi/4
vertical shift:3

The period is 4 pi since than is how much teta must increases to increase the argument,(theta/2 pi/4), by 2 pi.
The phase shift (to the right on a graph) is pi/4, not pi/4. That is how much the trig function shifts to the right. Think about it.
You got the vertical shift right.
