State the period, phase shift, and vertical shift of the function y=tan(theta/2-pi/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.
