# What are the important information needed to graph y= 3tan(2x - pi/3) ?

With the general equation $y = a \tan \left(b x - c\right) + d$, we can determine that $a$ is the amplitude, $\frac{\pi}{b}$ is the period, $\frac{c}{b}$ is the horizontal shift, and $d$ is the vertical shift. Your equation has all but horizontal shift.
Thus, the amplitude$= 3$, period$= \frac{\pi}{2}$, and horizontal shift$= \frac{\pi}{6}$ (to the right).
