/in /by

Question is find (fog)(x) and (gof)(x) and the domain of each of the following: a. ) f(x)=x+1, g(x)=3x²-2x-1
b) f(x)=6/x, g(x)=1/2x+1

Did i answer this correctly? Since there is no given value I assume the answers below would be what I am being asked for?

a.) (fog)(x)= (x+1)+(3x²-2x-1)

(gof)(x) = (3x²-2x-1)+(x+1)

b.) (fog)(x)=(6/x)+(1/2x+1)

(gof)(x) = (1/2x+1)+(6/x)
