Answer
Amplitude is 3
Period is $\pi$
Horizontal shift is 1
Work Step by Step
First, one must convert the equation to the following form $y=a\cdot $sin$(k(x-b))$, so it will be $y=3\cdot $sin$(2(x-1))$
Now one can find the data. The amplitude is $|a|$ which is 3 in this example. The period is found using $\frac{2\pi}{k}$, so $\frac{2\pi}{2}=\pi$. And the horizontal shift is represented by $b$, which, in this case, is $1$.
