$y$ has the standard graph of $sinx$ with peak-amplitude scaled by 3 units and period extended ("stretched") to $4pi$ .

$y =3sin(x/2)$

$y = 3 xx sin theta$ : where $theta = x/2$

Hence, the graph $y$ is the standard graph of $sinx$ with peak-amplitude scaled by 3 units and period extended ("stretched") to $4pi$ .

As can be seen in the graph of $y$ below.
graph{3sin(x/2) [-14.24, 14.24, -7.12, 7.12]}
