can you have a restriction for this problem since there is no variable in the denominator?:
(f * g)(x)=f(g(x))
=3x+1/2
the multiplication symbol (*) is an open circle
f(x)= x/2
g(x)= 3x+1

Each function has no restriction, so the composed function won't. (Indeed, it is because there's no x in the denominator).
