How can I plot the transfer function of this function B(s)=5s^3+30s^2+55s+30/A(s)=s^3+9s^2+33s+65

Are you sure you typed that correctly. It should probably be B(s)/A(s) = ...
What kind of plot are you trying to make?

What do you mean by "the domain?" That's not a common term in this context.

You can try with tf():
fun = tf([5 30 55 30],[1 9 33 65]); % B(s)=5s^3+30s^2+55s+30/A(s)=s^3+9s^2+33s+65
step(fun)
fun =
5 s^3 + 30 s^2 + 55 s + 30
--------------------------
s^3 + 9 s^2 + 33 s + 65
