Answer:
Step-by-step explanation:
Factor the 3 (the "b" value) out of the parenthesis and this will give you the proper phase shift:
[tex]y=tan3(x-70)+\frac{1}{2}[/tex]
This shows a phase shift of 70 to the right and then a vertical shift (aka. midline) of y = 1/2. The correct answer is the 3rd one down from the top.
