Could someone check this?

I did these problems recently but the answers weren't in the back of the book

2) f(y)= (y^2-3)/7
Domain: (-?,?)

4) g(x)= (-3)/(x-9)
Domain: (-?,9 ) ? (9,?)

6) h(y)= 2y/(6-y)
Domain: (-?,6) ? (6,?)

8) f(x)= 4x/(x+1)
Domain: (-?,-1) ? (-1,?)

10) h(x)= 4x/(x^2+16)
Domain: (-?,-4) ? (-4,?)
