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

Explanation:

#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.
