Answer 2

hint:
we can rewrite such function as below:
\[\huge y = 3\tan \left( {4\left( {x - \frac{\pi }{{12}}} \right)} \right)\]

Answer 3

now, you can read the period and the phase shift

Answer 4

period is pi/4 and phase shift is -pi/12 ??

Answer 5

that's right! Better is to write the phase shift without the minus sign

Answer 6

so is the phase shift positive or negative?

Answer 7

in our case it is negative, namely the function is shifted to the right

Answer 8

thanx
